摘　　要：对甲基丙烯酸羟丙酯(HPMA)/N-(11-羧基十一烷基)马来酰亚胺(CUMI)自由基共聚合体系进行研究,考察了共聚单体组成对共聚合反应转化率、共聚合初始反应速率、共聚物组成及分子量的影响.发现HPMA和CUMI共聚合体系可以在较宽的单体组成范围内得到交替共聚物;且当单体组成(HPMA/CUMI)的摩尔比为5/5时,共聚合初始反应速率最大.共聚单体对HPMA(M1)/CUMI(M2)在甲苯中的竞聚率分别为r1=0.01,r2=0.10.此外,采用1H NMR对共聚物进行了表征.The free radical copolymerization of hydroxypropyl methacrylate HPMA （ M1 ） and N - （ 11 - earboxyundeeyl ） maleimide CUMI （ M2 ） was carried out with benzoyl peroxides （BPO） as an initiator in toluene at 80 ℃. The copelymerization of HPMA with CUMI in toluene proceeded in a heterogeneous system to give an alternating eopelymer when the monomer of CUMI was over 50 mol% in the feed. It was found that the initial rate of eopelymerization （ Rp ） , eopelymer compositions, and the number - average molecular weight of copelymers, were dependent on the monomer composition and the maximum Rp was observed at about 50 tool% of CUMI in the feed. The monomer reactivity ratios were found tobe r1 = 0.01, r2 = 0.10 in tolueno. In addition, the copelymer was characterized by ^1H NMR spectrescopy. K
