ABS-POLYMERS OF HIGH NOTCHED IMPACT STRENGTH

摘要

This invention relates to a composition of matter comprising 100 parts by weight of an ABS polymer, 0.05 to 0.5 parts by weight of a liquid polymethyl phenyl siloxane or liquid polydimethyl siloxane having a viscosity from 20 to 100,000 cSt. at 20 degrees centigrade and 0.25 to 5 parts by weight of calcium stearate pentaerythritol tetrastearate, the bis-stearylamide of ethylene diamine or mixtures thereof. By this method it is possible to improve the physical properties of ABS-polymers.
