Abstract

PURPOSE: To prepare an unsaturated polyester having excellent resistance to hot water and chemicals, by reacting saturated polybasic acids consisting of isophthalic and terephthalic acids with polyhydric alcohols under pressure, thereafter by polycondensing the product with unsaturated polybasic acids (anhydrides).
