摘要：
ALIPHATIC DIPERESTERS OF ALKYNE DIOLS HAVING THE FORMULA:
R5-CO-O-O-C(-R1)(-R2)-(C*C)M-(CH2)P-(C*C)N-C(-R3)(-R4)-O-
O-CO-R6
WHERE R1, R2, R3 AND R4 ARE LOWER HYDROCARBON GROUPS, M AND N ARE 0 OR 1 WITH THE PROVISO THAT THEIR SUM IS ALWAYS AT LEAST ONE, P IS A POSITIVE INTEGER, AND R5 AND R6 ARE THE SAME OR DIFFERENT ALIPHATIC GROUPS OF FROM 1 TO 20 CARBON ATOMS ARE USEFUL AS CATALYSTS FOR THE FREE RADICAL INITIATED POLYMERIZATION OF POLYESTERS. USE OF THESE DIPERESTERS AS CATALYSTS ELIMINATE VARIOUS DISTORIONS IN THE STRUCTURE OF THE FINISHED MOLDED RESIN PRODUCT.
