Abstract: The present invention is a method for efficiently incorporating a nitrogen containing methine light absorber into a polyester resin. The method includes forming a reaction mixture comprising combining a diol component, a diacid component selected from the group consisting of dicarboxylic acids, dicarboxylic acid derivatives, and mixtures thereof, an antimony containing compound, a phosphorus containing compound, a metal containing compound, and a nitrogen containing methine light absorber. The reaction mixture is polymerized in a polycondensation reaction system. In another embodiment the light absorber is added while the reaction products of one reactor are being transferred to the next reactor in the polycondensation reaction system. The present invention is also directed articles made from the polyester resin.

Abstract: The present invention is a method of efficiently incorporating a UV inhibitor into a polyester resin. The method of the invention comprises forming a reaction mixture comprising a diol, a diacid component selected from the group consisting of dicarboxylic acids, dicarboxylic acid derivatives, and mixtures thereof, an antimony containing compound, a phosphorus containing compound, a metal containing compound selected, and a UV inhibitor. The reaction mixture is polymerized in a polycondensaton reaction system. In another embodiment of the present invention, the UV inhibitor is added while the reaction products from one reactor are transferred to the next reactor in the polycondensation reaction system.
