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 verses other titanyl oxalate catalysts and a novel polyester without the presence of antimony.

Abstract: The present invention comprises a polystannoxane catalyst, a curable composition containing the catalyst and a method of using the catalyst and curing the composition.
The curable composition comprises:

(i) a blocked isocyanate;
(ii) a functional component containing reactive hydrogen;
(iii) a polystannoxane catalyst for promoting the reaction of the blocked isocyanate with the functional component.
A co-catalyst may also be employed based on Cu, Zn, Ni, Zr, Ce, Fe, Co, V, Sb and Bi and especially oxides, salts or chelates of said metals. The invention also relates to a method for curing a blocked isocyanate at a low reaction temperature which comprises combining the catalyst with the blocked isocyanate and functional component and heating to a temperature less than about 180°C to obtain a cured urethane.
