POLYMER COMPOSITIONS CONTAINING AN ULTRAVIOLET LIGHT ABSORBING COMPOUND |
摘要 |
This invention relates to a polymer composition 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; (B) a salt comprising at least one suitable phosphorus-containing acid and at least one suitable basic organic compound, such as a hindered amine light stabilizer; (C) at least one ultraviolet light absorbing compound and optionally at least one phenolic antioxidant. A second embodiment of the present invention pertains to a blend 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) a salt comprising at least one suitable phosphorus-containing acid and at least one suitable basic organic compound; (C) at least one ultraviolet light absorbing compound and, optionally, at least one phenolic antioxidant; and (D) at least one polycarbonate. |
