  • Publication number: 20020065387
    Abstract: This invention relates to a method for manufacturing polyesters, in particular, to using a lithium titanyl oxalate as the catalyst for such reaction to provide fast reactions with excellent color properties for the resulting polyester. The present invention provides an improved method of producing polyester by the polycondensation of polyester forming reactants wherein the improvement comprises utilizing, as the polycondensation catalyst, lithium titanyl oxalate. The improved process produces a polyester of improved color versus other titanyl oxalate catalysts and a novel polyester without the presence of antimony.
