Abstract

PURPOSE: To prepare an unsaturated polyester having high impact strength and flexibility, and suitable as a coating material, by reacting an unsaturated alcohol, an unsaturated acid, a saturated alcohol and a saturated acid in the presence of a Pb-containing compound.
CONSTITUTION: An unsaturated acid such as fumaric acid, an unsaturated alcohol such as allyl alcohol, a saturated acid such as terephthalic acid, and a saturated alcohol such as ethylene glycol, are reacted together in the presence of a Pb-containing compound such as lead acetate, etc., at 150W210°C, and the reaction product is dehydrated at 150W230°C. The objective unsaturated polyester is prepared by the polycondensation of the dehydrated product. The amount of the Pb-containing compound is pref. 0.005W0.1 part (as Pb) per 100 parts of the reaction components.
