Brand of the polyester carbonate copolymer or terpolymer and a polycarbonate resin

摘要

A polymer blend comprises (a) 10-26 wt.% of a normally solid polyester catbonate copolymer of terpolymer contg. repeating units - (-ROCOR'COO)xROCOO- in which each R is independently arom. hydrocarbylene or inertly substd. aromatic hydrocarbylene, each R' is independently meta-or para-phenylene, and X is 0.05-10; and (b) 90-74 wt.% of a normally solid arom. hydrocarbylene. The mole % of ester in the blend is 10.22 based on the total moles of ester in carbonate gps.
