ABSTRACT:
This invention relates to polycarbonate compositions comprising:(A) at least one polycarbonate comprising repeating units derived from a dihydroxyaromatic compound or a dihydroxyaliphatic compound of the formula HO—Y—OH; and(B) at least one salt prepared from the reaction of one or more acidic phosphorus-containing compounds and one or more hindered amine light stabilizers. The polycarbonate compositions exhibit improved hydrolytic stability.
