AGENT FOR IMPROVING HEAT-RESISTANCE OF SYNTHETIC RESIN

摘要

PURPOSE:To provide an agent for improving the heat-resistance of a synthetic resin, consisting of a specific compound, and exhibiting excellent effect to the antistatic property, surface lubricity, color tone, mold releasability, acceleration of crystallization, etc. as well as heat-resistance when compounded to a synthetic resin. CONSTITUTION:A bisphenol compound is added with an alkylene oxide such as ethylene oxide, propylene oxide, etc., and then acylated with a 2-22C fatty acid to obtain the compound of formula [A is 2-22C alkyl; R<1> is residue of ethylene, propylene, styrene or mixed alkylene; X is -CH2-, -C(CH3)2-, -O- or -S-; m+n is 1-200]. 100pts.wt. of a synthetic resin (e.g. polyolefin, polyvinyl halide, ABS resin, etc.) is compounded with 0.1-5pts.wt., preferably 0.2-3pts.wt. of the modifier consisting of the above compound.
