<p>A method for efficiently incorporating a UV absorber into a polyester resin. The method includes forming a reaction mixture comprising 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 UV absorber. The reaction mixture is polymerized in a polycondensation reaction system. In another embodiment of the present invention, the UV absorber is, added while the reaction products from one reactor are transferred to the next reactor in the polycondensation reaction system. The present invention is also directed to novel UV absorbing compounds as well as articles made from the polyester resin.</p> |
