                                                                    Exhibit 99.1

                   POLYONE UPDATES 2005 THIRD-QUARTER OUTLOOK

    CLEVELAND, September 13 /PRNewswire-FirstCall/ -- PolyOne Corporation (NYSE:
POL), a leading global polymer compounding and North American distribution
company, today updated its outlook for the third quarter that will end September
30, 2005. This action is part of PolyOne's efforts to inform investors at
mid-quarter of any significant changes to major business drivers.

    Since PolyOne reported second-quarter results on July 28, 2005, three
factors are adversely affecting the outlook for the third quarter:

     - In North America, the anticipated increase in demand over the second
       quarter has not occurred.

     - Prior to Hurricane Katrina, natural gas and ethylene costs rose to
       higher-than-anticipated levels, driving higher raw material costs and
       placing additional pressure on product spreads (product selling prices
       over raw material costs).

     - The hurricane's immediate and longer-term negative effects from
       production and supply disruptions and from higher energy and derivative
       raw material costs are being assessed, but the full magnitude remains
       unknown.

    Entering the quarter, PolyOne anticipated fairly stable raw material pricing
and a counter-seasonal pickup in demand. Consistent with industry consensus,
PolyOne's view was that the unusual decline in North American second-quarter
demand was due largely to broad customer inventory reductions, and that demand
would improve in the third quarter. This demand momentum has not yet
materialized, and the Company now expects flat shipment volumes compared with
the second quarter, rather than the 1 percent to 3 percent increase in the
earlier outlook.

    European demand is tracking earlier expectations, and the Company continues
to experience strong shipment growth in Asia.

    The immediate impact of Hurricane Katrina is reflected largely in lowered
Resin and Intermediates (R&I) segment earnings expectations. The SunBelt
Chlor-Alkali plant in Macintosh, Alabama, lost a week of production, and
operations going forward are dependent upon railcar availability. Further, Oxy
Vinyls, LP in particular faces hurricane-driven natural gas and ethylene cost
increases, which are resulting in significantly higher operating costs and
pressure on product spreads. PolyOne expects logistical cost increases,
including fuel surcharges and rail system dislocations, to negatively affect all
North American operations for the near future.

    As a result of these factors, PolyOne expects that R&I segment operating
income should decrease significantly more from the second-quarter level than
previously thought. Hurricane Katrina's impact on the industry is dynamic and
continues to evolve.

    The July 28, 2005, outlook for PolyOne's discontinued operations, Specialty
Resins and Engineered Films, is unchanged.

    In the third quarter, the Company expects to generate positive operating
cash flow, although the level remains subject to the unknown variables described
above. Additionally, the recently amended credit facilities (as described in the
second-quarter 2005 Form 10-Q) assure adequate liquidity.

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.

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 provided 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.
