Title:

STABILIZER COMPOSITION FOR ORGANIC POLYMERIC MATERIALS CONTAINING 6-HYDROXYCHROMAN COMPOUNDS AND ORGANIC POLYMERIC MATERIAL COMPOSITIONS

Document Type and Number:

WIPO Patent Application WO/1999/018154

Kind Code:

A1

Abstract:

A stabilizer composition for organic polymeric materials, comprising (a) a compound represented by general formula (1) (wherein R?1¿ is C¿1?-C¿6? alkyl or C¿2?-C¿6? alkenyl; and R?2¿, R?3¿, R?4¿ and R?5¿ are each hydrogen or C¿1?-C¿4? alkyl) and (b) at least one member selected from the group consisting of phenolic antioxidants and phosphorus antioxidants at a specific ratio. The application of the stabilizer composition to organic polymeric materials can give stabilized organic polymeric material compositions excellent in not only heat resistance but also stability in processing.
