Abstract

A copolyester containing at least 10% by weight of each of (a) isophthalic acid or terephthalic acid or a mixture thereof, (b) an an aliphatic diol, preferably containing from 2-10 carbon atoms and (c) a saturated aliphatic polyhydric alcohol having at least three hydroxyl groups, is made by reacting component (c) with at least a portion of component (a) such that (c) is in excess and mixing the esterification reaction product thus formed with the balance of component (a) and component (b) and maintaining the mixture at a temperature of at least 160 DEG C. in the presence of from 0.01 to 5%, based on the total weight of components (a), (b) and (c), of an ester of titanium in which at least one organic radical containing from 1 to 20 carbon atoms is joined to the titanium atom through an oxygen atom, and removing water of esterification from the reaction mixture as esterification proceeds. The ester of titanium may be a titanium tetralkoxide, or an acylate thereof, or a chelate thereof, or a partially hydrolysed derivative thereof, or a quaternary salt thereof with ammonia or an alkali metal or an alkaline earth metal and containing a complex titanium hexalkoxy radical. In an example, glycerin is reacted with terephthalic acid in the presence of titanium tetraisopropoxide to form diglycerol terephthalate as an intermediate which is heated with ethylene glycol, terephthalic acid and titanium tetraisopropoxide to form a copolyester resin.
