FOR IMMEDIATE RELEASE



                    PolyOne Invests In Newly Created Centers
                           Of Manufacturing Excellence

- -    Engineered Materials Plants Are Focus of $12 Million Modernization
- -    Upgraded IT System Will Support New Manufacturing Network
- -    Three Engineered Materials Plants to Close by Second-Half 2002


CLEVELAND - June 21, 2001 - PolyOne Corporation (NYSE: POL) today announced the
formation of four CENTERS OF MANUFACTURING EXCELLENCE (CMEs), the first major
step in the Company's previously announced program to modernize its North
American Plastic Compounds and Colors (PCC) manufacturing network.

These centers, created to better serve the Company's engineered materials
customer base, will be upgraded with more than $12 million in new technology and
manufacturing equipment. PolyOne plans to invest a total of $45 million over the
next two years to reconfigure its North American engineered materials, vinyl
compound and colorant manufacturing facilities, all of which are part of its PCC
Group.

BUILDING A CUSTOMER-FOCUSED MANUFACTURING NETWORK
The newly announced CMEs for engineered materials are in Avon Lake, Ohio;
Dyersburg, Tenn.; Macedonia, Ohio; and Seabrook, Texas. These strategically
located facilities will be product-focused manufacturing sites dedicated to
specific customer needs. To meet current and projected needs, up to nine new
manufacturing lines will be installed at these sites and up to 65 positions will
be added.

The Company is studying a plan to also produce engineered materials at one of
its existing West Coast operating sites. PolyOne stressed that it remains
committed to serving its West Coast engineered materials customers.

Following modernization and consolidation at the CME sites, PolyOne said, it
will close three engineered materials plants. These moves will result in a
pre-tax earnings improvement of approximately $12 million annually, beginning in
2003.

The sites slated for closing are in Bethlehem, Pennsylvania; Corona, California;
and Houston, Texas. These plants are expected to close in the second half of
2002 as production is transferred gradually to the CMEs.

"We have a dedicated project team that has developed a very thoughtful, detailed
engineering and commercial plan to guide production transfers over time on a
product-by-product, customer-by-customer basis," said PolyOne Chairman and Chief
Executive Officer Thomas A. Waltermire.

"The net result for PolyOne will be a polymer compounding network of equipment,
technology and people second to none," said Waltermire. "The entire process is
being driven with our customers' interests in mind. All our efforts are geared
to helping our customers succeed."

The three engineered materials plant closings will be included as part of the
acquisition purchase accounting related to the consolidation of The Geon Company
and M.A. Hanna Company to form PolyOne. The purchase accounting accrual for cash
employee separation and plant phase-out costs totals $4.9 million. Approximately
200 positions will be eliminated with the closings.

Parallel to the manufacturing reconfiguration, PolyOne is redesigning its
business information system to support the new CMEs. The upgraded system is
expected to further improve PolyOne's reliability and the speed of its
communications and services. PolyOne will spend $25 million in 2001 to bring PCC
and several of its other business groups onto a common system platform by
January 2002.

ADDITIONAL ANNOUNCEMENTS DUE
PolyOne announced in April 2001 that it expects to achieve annual pre-tax
savings of $35 million to $50 million through the upgrade and expansion of some
manufacturing facilities and the simultaneous closing of others within PCC, its
largest business group.

The reconfiguration will soon extend to vinyl compounds and colorants.
Facilities in those PCC units are still under study. Further announcements of
additional CME sites will occur in coming months, once the Company reaches final
decisions on these sites and can assure that production transfers will occur
with no disruptions in customer service.

The Company expects to have its entire CME network operating by the end of 2002.
PolyOne will reduce the number of PCC manufacturing sites by at least one-third
from the 34 that it had at the beginning of 2001.
