                                    Part I


Item 1. Business

General-Union Carbide operates in two business segments of the chemicals and 
plastics industry, Specialties & Intermediates and Basic Chemicals & Polymers. 
Specialties & Intermediates converts basic and intermediate chemicals into a 
diverse portfolio of chemicals and polymers serving industrial customers in 
many markets. This segment also provides technology services, including 
licensing, to the oil and gas and petrochemicals industries. The Basic 
Chemicals & Polymers segment converts hydrocarbon feedstocks, principally 
liquefied petroleum gas and naphtha, into polyethylene, polypropylene, 
ethylene oxide and ethylene glycol for sale to third-party customers, as well 
as propylene, ethylene, ethylene oxide and ethylene glycol for consumption by 
the Specialties & Intermediates segment. The profitability of the Basic 
Chemicals & Polymers segment of the chemicals and plastics industry is highly 
cyclical, whereas that of the Specialties & Intermediates segment is less 
cyclical. Consequently, Union Carbide's results are subject to the swings of 
the business cycle in both the highly volatile Basic Chemicals & Polymers 
segment and the less volatile Specialties & Intermediates segment. See page 1, 
pages 6 through 8, and "Summary and Outlook" on pages 9 through 11 of the 1997 
annual report to stockholders for further information about Union Carbide's 
businesses, and Note Five on pages 28 and 29 of the 1997 annual report to 
stockholders for financial information about Union Carbide's business 
segments.

Union Carbide does not produce against a backlog of firm orders; production is 
geared primarily to the level of incoming orders and to projections of future 
demand. Inventories of finished products, work in process and raw materials 
are maintained to meet delivery requirements of customers and Union Carbide's 
production schedules.

At year-end 1997, 11,813 people were employed in the manufacturing facilities, 
laboratories and offices of the corporation and its consolidated subsidiaries 
around the world.

Raw Materials, Products and Markets-See information herein and in the 1997 
annual report to stockholders on pages 6 through 8. The products of Union 
Carbide are principally sold by its own sales force, directly to customers.

Union Carbide believes it has contracts or commitments for, or readily 
available sources of, hydrocarbon feedstocks and fuel supplies to meet its 
anticipated needs in all major product areas. The corporation's operations are 
dependent upon the availability of hydrocarbon feedstocks and fuels which are 
purchased from diverse domestic and international sources, including 
independent oil and gas producers as well as integrated oil companies.

The availability and price of hydrocarbon feedstocks, energy and finished 
products are subject to plant interruptions and outages and to market and 
political conditions in the U.S. and elsewhere. Operations and products at 
times may be adversely affected by legislation, government regulations, 
shortages, or international or domestic events.

The business segments of Union Carbide are not dependent to a significant 
extent upon a single customer or a few customers.

Patents; Trademarks; Research and Development-Union Carbide owns a large 
number of United States and foreign patents that relate to a wide variety of 
products and processes, has pending a substantial number of patent 
applications throughout the world, and is licensed under a number of patents. 
These patents expire at various times over the next 20 years. Such patents and 
patent applications in the aggregate are material to Union Carbide's 
competitive position. No one patent is considered to be material; however, the 
patent portfolio relating to the UNIPOL process technology is, in the 
aggregate, considered to be material. Union Carbide also has a large number of 
trademarks. The UNION CARBIDE, UCAR and UNIPOL trademarks are material; no 
other single trademark is material.

                                    - 1 -




                                Part I (Cont.)

Essentially all of Union Carbide's research and development activities are 
company-sponsored. The principal research and development facilities of Union 
Carbide are indicated in the discussion of Properties (Item 2) of this Form 
10-K report. In addition to the facilities specifically indicated there, 
product development and process technology laboratories are maintained at some 
plants. Union Carbide expensed $157 million in 1997, $159 million in 1996, and 
$144 million in 1995 on company-sponsored research activities to develop new 
products, processes, or services, or to improve existing ones.

Environment-See Costs Relating to Protection of the Environment on pages 12 
and 13 of the 1997 annual report to stockholders and Note Seventeen on pages 
39 and 40 thereof.

Insurance-Union Carbide's policy is to obtain public liability and other 
insurance coverage at terms and conditions and a cost that management 
considers fair and reasonable. Union Carbide's management believes it has a 
prudent risk management policy in effect, and it periodically reviews its 
insurance coverage as to scope and amount and makes adjustments as deemed 
necessary. There is no assurance, however, that Union Carbide will not incur 
losses beyond the limits, or outside the coverage, of its insurance. Such 
insurance is subject to substantial corporate retentions.

Competition-Each of the major product and service areas in which Union Carbide 
participates is highly competitive. In some instances competition comes from 
manufacturers of the same products as those produced by Union Carbide and in 
other cases from manufacturers of different products which may serve the same 
markets as those served by Union Carbide's products. Some of Union Carbide's 
competitors, such as companies principally engaged in petroleum operations, 
have more direct access to hydrocarbon feedstocks, and some have greater 
financial resources than Union Carbide.

The Specialties & Intermediates segment is characterized by differentiated 
products and is less subject to external changes in supply/demand 
relationships than the Basic Chemicals & Polymers segment. In this segment, 
competition is based primarily on product functionality and quality, with the 
more unique products commanding significant price premiums.

The Basic Chemicals & Polymers segment is characterized by large volume 
commodity products and is subject to external changes in supply/demand 
relationships, including changes in the strength of the overall economy, 
customer inventory levels, industry manufacturing capacity and operating rates 
and raw material feedstock costs. Participants in this segment compete for 
business primarily on the basis of price and efficient delivery systems.

See pages 6 through 8 of the 1997 annual report to stockholders for 
information about each segment's principal products, competitive position and 
major competitors.

Union Carbide is a major marketer of petrochemical products throughout the 
world. Products that the corporation markets are largely produced in the 
United States, while products marketed by the corporation's joint ventures are 
principally produced outside the United States. Competitive products are 
produced throughout the world.

Union Carbide's international operations face competition from local producers 
and global competitors and a number of risks inherent in carrying on business 
outside the United States, including risks of nationalization, expropriation, 
restrictive action by local governments and changes in currency exchange 
rates, in addition to the risks stated above.

                                Part I (Cont.)

Item 2. Properties

In management's opinion, current facilities, together with planned expansions, 
will provide adequate production capacity to meet Union Carbide's planned 
business activities. Capital expenditures are discussed on pages 16 and 17 of 
the 1997 annual report to stockholders.

Listed below are the principal manufacturing facilities operated by Union 
Carbide worldwide. Research and engineering facilities are noted. Most of the 
domestic properties are owned in fee. Union Carbide maintains numerous 
domestic sales offices and warehouses, substantially all of which are leased 
premises under relatively short-term leases. All principal international 
manufacturing properties are owned or held under long-term leases. 
International administrative offices, technical service laboratories, sales 
offices and warehouses are owned in some instances and held under relatively 
short-term leases in other instances. The corporation's headquarters is 
located in Danbury, Connecticut, and is leased.

Principal domestic manufacturing facilities and the principal products 
manufactured there are as follows:

and cash flows for each of the years in the three-year period ended December

stockholders. These consolidated financial statements and our report thereon 
are incorporated by reference in the Annual Report on Form 10-K for the year 
1997. In connection with our audits of the aforementioned consolidated 
financial statements, we also have audited the related financial statement

express an opinion on this financial statement schedule based on our audits.

In our opinion, such financial statement schedule, when considered in relation 
to the basic consolidated financial statements taken as a whole, presents 
fairly, in all material respects, the information set forth therein.
