                   PolyOne Updates 2007 Second-quarter Outlook


CLEVELAND - June 29, 2007 - PolyOne Corporation (NYSE: POL) today updated its
outlook for the second quarter ending June 30, 2007.

The Company expects second-quarter sales to rebound sequentially by 4 percent to
6 percent over the first quarter of 2007. Compared with the second quarter of
2006, PolyOne anticipates this year's second-quarter sales will be flat to
slightly up, despite weakness in construction-related and automotive end
markets.

PolyOne anticipates strong year-over-year sales and earnings increases for its
International Color and Engineered Materials segment, with double-digit growth
in both Europe and Asia. Additionally, the Company anticipates realizing modest
sequential and year-over-year second-quarter gross margin improvement in its
operating businesses, excluding the Vinyl Business segment. This achievement
reflects benefits from the continued implementation of the four core components
of PolyOne's growth strategy: specialization, globalization, operational
excellence and commercial excellence.

Income performance from PolyOne's vinyl chain business segments is projected to
be weak as a result of poor demand in construction-related end markets and
escalating raw materials. Even though second quarter sales for PolyOne's Vinyl
Business segment are forecast to increase sequentially, significant raw material
cost increases are anticipated to materially decrease segment earnings results
compared with the first quarter of 2007. In the Resin and Intermediates segment,
PolyOne projects a modest sequential earnings improvement for Oxy Vinyls, LP.
SunBelt's chlor-alkali margins, on the other hand, are projected to remain
relatively strong and advance moderately compared with first-quarter 2007
levels.

Other Considerations:

o    Compared with the second quarter of 2006, the Company anticipates Corporate
     and other expenses will reflect a net increase of approximately $5.7
     million primarily due to prior year benefits from litigation settlements
     and adjustments to associated operating reserves.

o    The Company will record a higher effective tax rate in the second quarter
     of 2007 compared with the same period in 2006, due to the reversal of a
     portion of the Company's deferred tax asset allowance in the second quarter
     of 2006. This will not affect cash flow because PolyOne has remaining
     domestic net operating loss carry-forwards. Cash taxes will continue to be
     associated principally with non-U.S. earnings.



o    On June 27, 2007, PolyOne completed the redemption of $100 million in
     aggregate principal amount of its 10.625 percent Senior Notes due 2010.
     Upon completion of this redemption, $141.37 million of these notes will
     remain outstanding. Prepayment and other costs associated with this
     transaction are anticipated to be approximately $7 million.
