STABILIZER FOR POLYPROPYLENE BASED RESIN OR POLYSTYRENE BASED RESIN, AND METHOD FOR MANUFACTURING THE SAME, COMPOSITION USING THE SAME, AND STABILIZATION METHOD OF THE POLYPROPYLENE BASED RESIN OR THE POLYSTYRENE BASED RESIN

摘要

PROBLEM TO BE SOLVED: To provide a stabilizer capable of further improving process stability of the thermoplastic polymer compared with the conventional one, by compounding the stabilizer into the thermoplastic polymer, and a method of manufacturing the same.;SOLUTION: There are provided the stabilizer containing, as a main component, a bisphenol monoester, and a bisphenol-based compound, wherein the area of the bisphenol-based compound is 0.15 to 70 when the area of the bisphenol monoester is set to be 100 in a chromatograph obtained by liquid chromatography analysis of the stabilizer, the method of manufacturing the same, a thermoplastic polymer composition containing the stabilizer, and stabilization method of the thermoplastic polymer using the stabilizer.;COPYRIGHT: (C)2012,JPO&INPIT
