Exhibit 99.1

                                                                    NEWS RELEASE

                   POLYONE UPDATES 2007 FIRST-QUARTER OUTLOOK

CLEVELAND - March 23, 2007 - PolyOne Corporation (NYSE: POL) today updated its
outlook for the first quarter ending March 31, 2007.

Following is PolyOne's current view of business conditions:

    Operating Segments Overview - Consistent with the Company's business outlook
    at the end of January 2007, first-quarter sales are expected to rebound
    approximately 10 percent over the fourth quarter of 2006, but remain
    generally sluggish due to continuing slowness in construction-related and
    automotive end markets. Consequently, the Company projects that total sales
    will decrease between 2 percent and 4 percent compared with a record 2006
    first quarter. Lower Vinyl Business demand in North America primarily
    accounts for this decline. Conversely, PolyOne anticipates strong,
    double-digit year-over-year sales growth for its international operations.
    Additionally, the Company is realizing sequential gross margin improvement
    from its operating segments, as anticipated. This improvement reflects
    benefits achieved from the specialization and globalization components of
    PolyOne's strategy, which are underpinned by capabilities developed through
    commercial and operational excellence.

    Resin and Intermediates equity investments - The Company projects that lower
    margins and volumes will significantly reduce the earnings contribution from
    Oxy Vinyls, LP and SunBelt Chlor-alkali Partnership compared with the record
    first quarter of 2006. Given the extent to which continuing weakness in
    construction-related end markets has adversely affected volumes for both
    OxyVinyls and SunBelt, segment earnings will likely erode from
    fourth-quarter 2006 levels. Polyvinyl chloride (PVC) resin product spreads
    are expected to narrow due to lower average PVC prices. Chlor-alkali
    margins, however, are projected to remain relatively strong.

    OTHER CONSIDERATIONS:

    o   In the first quarter of 2006, PolyOne realized approximately $9 million
        of benefit from non-recurring adjustments to certain operating reserves
        and litigation settlements. The Company does not anticipate that it will
        benefit materially from such items in the first quarter of 2007.

    o   Because of cumulative positive domestic earnings over the past three
        years, PolyOne will return to reporting domestic tax expense in its
        financial statements. This change in accounting treatment will not
        affect cash flow due to PolyOne's net operating loss position, which was
        $269 million as of December 31, 2006. Cash taxes will continue to be
        associated principally with non-U.S. earnings.

We cannot guarantee that any forward-looking statement will be realized,
although we believe we have been prudent in our plans and assumptions.
Achievement of future results is subject to risks, uncertainties and inaccurate
assumptions. Should known or unknown risks or uncertainties materialize, or
should underlying assumptions prove inaccurate, actual results could vary
materially from those anticipated, estimated or projected. Investors should bear
this in mind as they consider forward-looking statements.

We undertake no obligation to publicly update forward-looking statements,
whether as a result of new information, future events or otherwise. You are
advised, however, to consult any further disclosures we make on related subjects
in our reports on Form 10-Q, 8-K and 10-K that we provide to the Securities and
Exchange Commission. You should understand that it is not possible to predict or
identify all risk factors. Consequently, you should not consider any list to be
a complete set of all potential risks or uncertainties. (Ref. #32207)
