PROCESS FOR PRODUCTION OF POLYOLEFIN-POLYESTER GRAFT COPOLYMER

摘要

A process for producing a polyolefin-polyester graft copolymer by melt-kneading, in the presence of a minor part of water, a polyester having both an intrinsic viscosity of 0.5 to 1.8 and a concentration of terminal carboxyl group of 10 to 100 meq/Kg with a polyolefin containing 0.2 to 5 mol % carboxyl or epoxy group and having a weight average molecular weight of 8,000 to 140,000.
