POLYCAPROLACTONE-GRAFTED EPOXY-MODIFIED COPOLYMER AND ITS PRODUCTION

摘要

PURPOSE: To obtain the title copolymer which is an excellent compatibilizer for a polymer blend comprising a thermoplastic resin compatible with polycaprolactone and an engineering plastics by mixing a specified epoxy- modified copolymer with a modified polycaprolactone in a specified ratio. ;CONSTITUTION: This copolymer comprises 2-98 pts.wt. epoxy modified copolymer comprising an unsaturated epoxy monomer (e.g. glydicyl methacrylate) and at least one copolymerizable vinyl monomer (e.g. styrene) and 98-2 pts.wt. modified polycaprolactone having one carboxyl group or one hydroxyl group in the molecule (e.g. a compound prepared by reacting ε-caprolactone with butanol).;COPYRIGHT: (C)1993,JPO&Japio
