摘要

<,正,>, Epichlorohydrin （ECH） was polymerized with a rare earth catalytic system: Nd （i-OPr）,3,-Al （i-Bu）,3,. The effects of Al/Nd molar ratio, solvents, the polymerization time and temperature,the aging time and temperature of the catalyst preparation were studied. The results showed thatat a low Al/Nd molar ratio （4） of the Nd（i-OPr）,3,-Al（i-Bu）,3, system ECH polymerized at a lowtemperature （248K） with a high conversion. The average molecular weight ofpolyepichlorohydrin （PECH） ranged from 1×10,5, to 3×10,5,.
