Flexsys Files Patent-Infringement Complaint With U.S. International Trade
Commission Against Sinorgchem, KKPC and Kumho Tire

ST. LOUIS, May 12, 2008 (PRIME NEWSWIRE) -- Flexsys America L.P., a subsidiary
of Solutia Inc. (NYSE:SOA), today announced it has filed a new complaint with
the U.S. International Trade Commission (ITC) against Sinorgchem Co., Shandong;
Korea Kumho Petrochemical Co., Ltd. (KKPC); Kumho Tire Co., Inc.; and Kumho Tire
USA, Inc. This complaint asserts that the importation of Sinorgchem's 4-ADPA or
any antidegradants made from its 4-ADPA into the United States violates section
337 of the U.S. Tariff Act, due to Sinorgchem's infringement upon Flexsys'
patents for the production of 4-ADPA and its intermediates.

"Flexsys invests significantly in the discovery, development and
commercialization of manufacturing processes for rubber chemicals," said Jim
Voss, president of Flexsys and senior vice president of Solutia Inc. "When our
competitors attempt to illegally misappropriate our patented technology, we will
continue to take aggressive action including the enforcement of our legal rights
on a global scale."

In this new case, Flexsys seeks an exclusion order barring the importation of
Sinorgchem's 4-ADPA as well as 6PPD made from Sinorgchem's 4-ADPA into the
United States, including that manufactured by KKPC. A separate exclusion order
continues to be in effect for Sinorgchem material as a result of an additional
case that Flexsys already is pursuing before the ITC against Sinorgchem.

Flexsys also has a civil patent infringement case against Kumho Tire, KKPC and
Sinorgchem. This case is currently pending in U.S. District Court for the
Northern District of Ohio.

The technology at issue in this case relates to environmentally friendly methods
for preparing compounds used in the manufacture of rubber products such as
tires, belts and hoses. These compounds prevent premature degradation of rubber
due to exposure to sun, heat, ozone and other factors. One such antidegradant is
6PPD, which is manufactured and sold by Flexsys under the brand name
Santoflex(r) 6PPD. The material known as 4-ADPA is an intermediate compound used
in the production of 6PPD.

Flexsys products play an important role in the manufacture of tires and other
rubber products, such as belts, hoses, seals and footwear. Flexsys is a global
business with offices, manufacturing facilities and technology centers around
the world. Flexsys has annual sales of more than $650 million, about two-thirds
of which take place outside the United States.
