CA 2479130

A process for making unsaturated polyesters from 2-methyl-1,3-propanediol (MPD) is disclosed. The process comprises reacting one equivalent of an aromatic diacid with about two equivalents of MPD to produce an ester diol and then reacting one equivalent of the ester diol with from about 1.1 to about 1.9 equivalents of maleic anhydride to produce the polyester. The polyester has a fumarate/maleate ratio of 90/10 or greater.

L'invention concerne un procédé de fabrication de polyesters insaturés à partir d'un 2-méthyl-1,3-propanediol (MPD). Le procédé consiste à faire réagir un équivalent d'un diacide aromatique avec environ deux équivalents de MPD afin d'obtenir un ester de diol puis à faire réagir un équivalent de l'ester de diol avec environ entre 1,1 et 1,9 équivalents d'anhydride maléïque afin d'obtenir le polyester. Le polyester présente un rapport fumarate/maléate de 90/10 ou plus.
