Polycarbonate compositions having improved chemical resistance, articles formed thereof, and methods of manufacture

Abstract

A polycarbonate composition includes: 10 to 99 wt % of one or more bisphenol A polycarbonate homopolymers based on the total weight of the polycarbonate composition; a poly(carbonate-siloxane) having a siloxane content of 30 to 70 wt %, preferably 35 to 65 wt %, based on the total weight of the poly(carbonate-siloxane), optionally wherein the poly(carbonate-siloxane) is a poly(carbonate-siloxane) elastomer, in an amount effective to provide a total siloxane content of 0.5 to 10 wt % based on the total weight of the polycarbonate composition; and wherein a sample of the composition has improved chemical resistance as compared to a reference composition.
