REACTIVE THERMOPLASTIC RESIN COMPOSITION AND MANUFACTURING METHOD THEREOF

摘要

A reactive thermoplastic resin composition, comprising the following components in portion by mass: 15-85 portions of polycarbonate resin; 15-85 portions of polybutylene terephthalate resin; 0.05-5 portions of ester exchange inhibitor; 0-30 portions of impact modifier; 0-5 portions of additive; the polybutylene terephthalate has an intrinsic viscosity of 0.6-1.5 dl/gr and an end-COOH content of < 50 meq/kg. The present invention, by designing components of the composition, then combining optimization of an extrusion process and controlling the degree of transesterification, constructs a special micro-phase structure, and the obtained resin composition has an excellent stiffness and modulus under a quasi-static state and exhibits an excellent toughness and energy absorption property when subject to a high speed surface impact at a low temperature.
