Abstract: Disclosed are polymer blends comprising a mixture of (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; (B) at least one phosphite ester compound; and (C) at least one hindered amine light stabilizer. The polymer blends exhibit improved color, especially when used as a component of a polyester/polycarbonate blend.
