method for incorporating a uv light absorber compound into a polyester |
| abstract |
A method for incorporating a UV light absorber compound into a polyester, and the thermoplastic article of the invention relates to a method for incorporating a UV light absorber compound into a polyester prepared using direct esterification of reagents selected from a dicarboxylic acid and a diol. . The method comprises reacting the reactants in an esterification reactor under conditions sufficient to form an esterified product including at least one of an ester, an oligomer, or mixture having an ester and a low molecular weight polyester blend, polymerizing the esterified product into a polycondensation reactor to form a polyester; and adding the UV absorbing compound to the esterified products when at least 50% of the carboxy groups initially present in the reactants have been esterified to obtain a polyester incorporated UV absorbing compound yield of more than 25%. Articles using the UV protected polyester prepared by the method of the present invention are further described. |
