Trivalent antimony catalyst |
| abstract |
A novel antimony catalyst for polyester condensation reactions is described comprising trivalent antimony having its valences occupied by dianion radicals of 1,2-diols and anion radicals or organic carboxylic acids. The molar ratio of antimony to dianion radical of 1,2-diol to anion radical of organic carboxylic acid is 1:1:1. The antimony compound is prepared by reacting a mixture of a 1,2-diol and a trivalent antimony reactant represented by the formula; R2 Sb ANGLE R1 R2 wherein Sb is antimony, R1 is an anion radical of an organic carboxylic acid; and R2 is selected from the group consisting of anions of alcohols, anions of organic carboxylic acids and mixtures thereof. |
