POLYESTER COMPOSITIONS

摘要

Disclosed are polymer compositions comprising: (A) at least one polyester prepared by the reaction of at least one diol with at least one dicarboxylic acid or dialkyl ester thereof in the presence of a metallic catalyst; and (B) at least one salt prepared from the reaction of one or more acidic phosphorus-containing compounds and one or more basic organic compounds which contain nitrogen. The polyester compositions exhibit improved color, especially when used as a component of a polyester/polycarbonate blend. Also disclosed are polymer compositions comprising a polycarbonate in combination with components (A) and (B).
