Summary: | The present invention relates to a novel catalyst complex for catalysing esterification and trans-esterification reactions, comprising: (i) a polymeric titanium glycolate having the formula [TiO4(CH2)4]n wherein n = 1 to 200; and (ii) an alkali metal glycolate; wherein the molar ratio of the polymeric titanium glycolate and the alkali metal glycolate is about 1.25:1 to about 100:1, preferably about 1.25:1 to about 10:1; and to a process for esterification of a dicarboxylic acid compound and an dialcoholic compound, followed by polycondensation to form a polyester. |
