BISPHENOL MONOESTER-BASED STABILIZER COMPOSITION, THERMOPLASTIC POLYMER COMPOSITION AND METHOD OF MANUFACTURING THE SAME, THERMOPLASTIC POLYMER MOLDED ARTICLE, AND USE OF BISPHENOL MONOESTER-BASED STABILIZER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a bisphenol monoester-based stabilizer composition that can improve resistance to discoloration at high temperature compared with a conventional one, a thermoplastic polymer composition improved in resistance to discoloration at high temperature using the same, and a method of manufacturing the thermoplastic polymer composition, a thermoplastic polymer molded product, and a method of stabilizing the thermoplastic polymer.;SOLUTION: Disclosed are a bisphenol monoester-based stabilizer composition mainly comprising a bisphenol monoester-based compound, and containing a compound represented by the formula in an area percentage of 0.1-3% as measured by analysis through liquid chromatography, a thermoplastic polymer composition and a method of manufacturing the thermoplastic polymer composition, a thermoplastic polymer molded product, and the use of the bisphenol monoester-based stabilizer composition for improving the resistance to discoloration at high temperature of the thermoplastic polymer.;COPYRIGHT: (C)2009,JPO&INPIT
