摘　　要：用溶液聚合方法合成了一系列单体配比不同的丙烯腈-甲基丙烯酸八乙氧基甲酯(简称MAMG)的共聚物。对共聚物进行了表征,并测定了吸湿率和上色率。实验结果表明,吸湿率和上色率随共聚物中第二单体MAMG含量的增加而升高,而共聚物的T_(?)随组成中MAMG含量的增加而降低。A series of copolymers of acrylonitrile(AN)/polyethylene glycol methyl methacrylate(MAMG) were prepared. The effects of the concentration of monomers and initiator, temp., polymerization time on polymer molecular weight were investigated. The hygroscopicity and the dveability of the copotymers were higher than those of homopolymer, and the higher content of MAMG was in the copolymer, the higher hygroscopicity and dveability of copolymer. Also, the polymers were characterized by IR, ~1H-NMR, elementary analysis, DSC etc.
