Low temp. moulding thermoplastic polyester compsn. - contains organo-phosphorus acid salts as nucleating agent and di:ketone or epoxidised ester as plasticiser

摘要

Improved compsn. for low temp. moulding comprises (a) a thermoplastic polyester, (b) a nucleating agent comprising a metal salt of an organophosphonic, organophosphinic or organophosphorous acid, (c) a plasticiser comprising a 14-43C beta-diKetone, an epoxidised ester of oleic acid or tall oil fatty acid or an ester of the acid known as EMPOL (RTM), and opt. (d) a filler or reinforcing agent. Compsn. has good mouldability at temp. less than 90 deg.C. The mouldings have good surface and physical properties.
