摘要： POLYESTER RESINS OF INCREASED FLEXIBILITY AND STRENGTH ARE OBTAINED BY MIXING USUALLY LIQUID, UNSATURATED POLYESTERS WITH CERTAIN, USUALLY LIQUID, POLYMERIZABLE POLYDIENE ETHYLENICALLY-UNSATURATED ESTERS HAVING TERMINAL, ALLYLIC, ACYLOXY GROUPS, SUCH AS ACRYLYLOXY, WHICH ARE TERMINALLY ETHYLENICALLY-UNSATURATED, THEREBY FORMING USUALLY LIQUID POLYMERIZABLE COMPOSITIONS WHICH ARE POLYMERIZABLE TO SOLID POLYMERS. COMMERCIAL UNSATURATED POLYESTER RESINS CONTAINING 0 TO ABOUT 75% BY WEIGHT OF STYRENE CAN BE USED. FROM ABOUT 5 TO 95% OF THE POLYMERIZABLE POLYDIENE ETHYLENICALLY-UNSATURATED ESTER CAN BE USED IN THE COMPOSITION, ALTHOUGH USUALLY ABOUT 10 TO 50% BY WEIGHT IS PREFERRED.
