Patent number: 7541407Abstract: A method for incorporating a UV light absorbing compound into a polyester prepared using direct esterification of reactants selected from a dicarboxylic acid and a diol. The method comprises reacting the reactants in an esterifying 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 mixture of low molecular weight polyester; polymerizing the esterified product in 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 yield of UV absorbing compound incorporated into the polyester of greater than 25%. Articles utilizing the UV protected polyester prepared by the method of the invention are additionally disclosed.Type: GrantFiled: May 27, 2004Date of Patent: June 2, 2009Assignee: Eastman Chemical CompanyInventors: Perry Michael Murdaugh, Sr., Earl Edmondson Howell, Jr., Cory Lee Wells, Max Allen Weaver, Jason Clay Pearson
