Abstract

PURPOSE: To prepare the title resin having high solubility of a polymerizable monomer, giving a molded article with excellent transparency and heat resistance, and suitable for the cast molding, etc., by reacting a diol compound obtained by the addition of terephthalic acid and epihalohydrin, with an unsaturated polybasic acid
CONSTITUTION: The objective unsaturated polyester resin is prepared by (1) reacting 1 mole of terephthalic acid with 2 moles of an epihalohydrin to obtain a diol compound, and (2) condensing the diol compound with an unsaturated polybasic acid such as fumaric acid, etc., and if necessary, with a saturated polybasic acid (e.g. succinic acid) and/or a polyhydric alcohol (e.g. ethylene glycol) in the presence of a catalyst such as lead salt of titanyl oxalate, etc., pref. at 150W240°C.
