Abstract

This invention relates to thermoplastic polycarbonate molding materials having improved flame resistance and hydrolysis resistance. These materials comprise intimate blends of aromatic high molecular weight polycarbonates and about 0.5 to 50 wt. % of polyphenylene sulphides. This invention also relates to a process for improving the flame resistance and hydrolysis resistance of aromatic polycarbonates by intimately blending them with about 0.5 to 50 wt. % polyphenylene sulphide.
