COPOLYMERIZATION OF EPOXIDES WITH i-Bu3Al-H2O-Zn(acac)2 SYSTEM
环氧化合物以三异丁基铝-水-双(2,4-戊二酮基)锌水合物为催化剂的共聚

The terpolymerization of epichlorohydrin, ethylene oxide and propylene oxide was studied by using i-Bu3Al-H2O-Zn(acac)2 system as catalysts. The vulcanizates of the terpolymers have good properties in which low-temperature resistance is comparable to, while its oil resistance is superior to 18-nitrile, and its ozone resistance is much better than nitrile rubbers.
