HEAT-PROOF ADDITIVES FOR A POLYMER RESIN COMPOSITION CONTAINING SPECIFIC THIO COMPOUND HAVING EXCELLENT HEAT STABILITY, AND A POLYMER RESIN COMPOSITION COMPRISING THE SAME

摘要

PURPOSE: A heat-proof additives for a polymer resin composition is provided to maintain thermal stability by using small amount and to be very environment-friendly because of volatility lower than existing heat-proof additives.;CONSTITUTION: A heat-proof additives a thio compound represented by chemical formula 1. In here, R1 is -Ch2SR2, R2 is a linear, branched or cyclic C5-16 alkyl group or C6-16 aromatic group, n is an integer satisfying 1=n=20. Number average molecular weight of the thio compound is 400-5,000. The polymer resin composition comprises 100.0 parts by weight of polymer resin, 0.01-5 parts by weight of the heat-proof additives. The polymer resin is one or more kinds selected from an ethylene polymer, a propylene polymer, a styrene polymer, a urethane polymer, a styrene-acrylonitrile copolymer, and an acrylonitrile-butadiene-styrene block copolymer.;COPYRIGHT KIPO 2013
