Title:

STABILIZER CONTAINING VITAMIN E FOR ORGANIC POLYMERIC MATERIAL

Document Type and Number:

WIPO Patent Application WO/2000/000540

Kind Code:

A1

Abstract:

A stabilizer composition for organic polymeric materials which comprises a compound represented by general formula (1) (wherein R?1¿, R?2¿, and R?3¿ are the same or different and each represents hydrogen or methyl), a phenolic antioxidant, and a phosphorus compound antioxidant, wherein the compound represented by formula (1) is contained in a specific amount relative to the sum of the three ingredients. By using the composition as a stabilizer for an organic polymeric material, a stabilized organic polymeric material can be provided which is excellent in heat resistance and especially in processing stability.
