摘要

本工作研完了末端为甲基丙烯酸酯型的聚环氧乙烷大单体与丙烯酸乙酯的溶液自由基共聚。结果表明

大单体接枝效率和共聚物分子量受单体总浓度、投料比、大单体分子量及引发剂等的影响

接枝效率最高可达90％以上

分子量可在5-15×104范围内变化。丙烯酸乙酯与大单体共聚的竞聚率为0.83。共聚物用萃取法精制后

用IR、1H-NMR、裂解色谱、GPC和膜渗透压计等进行了表征。证实产物有预期的规整接枝共聚物结构。平均接枝数为2—11。

Abstract

Copolymerization of o-methacryloyl polyoxyethylene macromers with ethyl acrylate (EA) in benzene using AIBN as initiator was studied. The effects of molecular weight of the macromers

charging ratio of the macromer to EA

total monomer concentration and amount of initiator on the grafting efficiency and molecular weight of the copolymers were reported. The highest grafting efficiency can reach above 90% and molecular weight of the copolymers varied from 5×104 to 15×104.Reactivity ratio of EA with the macromer was determined to be 0.83.The graft copolymers were purfied with extractions and the purified products were cha-racterized with IR

1H-NMR

PGC

GPC and membrane osmometry. The average grafting number of the copolymers varied from 2 to 11.
