POLYCARBONATE MOLDING COMPOSITIONS AND ARTICLES WITH IMPROVED SURFACE AESTHETICS

摘要

A thermoplastic polymer molding composition useful for producing an article, where the molding composition comprises a polyorganosiloxane-polycarbonate block copolymer and a flow modifier; wherein the flow modifier is at least one selected from the group consisting of a polyalkylene glycol, a low weight average molecular weight polycarbonate polymer, or mixtures thereof; and further wherein the flow modifier reduces surface imperfections when molded into the article.
