摘　　要：以偶氮二异丁腈(AIBN)为引发剂,在65℃下引发降冰片烯(NBE)与N-环己基马来酰亚胺(CHMI)的自由基不开环共聚合反应.用元素分析的方法测定在甲苯和氯仿溶剂中,不同单体配比时聚合反应初期共聚组成,用斜截法计算其竞聚率分别为r1=0,r2=0.5和r1=0,r2=0.39.Radical no ring-open copolymerization of norbornene （NBE） and N-cyclohexylmaleimide （CHMI） was carried out with 2,2-Azobisjsobutyronitrile （AIBN） as an initiator at 65 ℃. Teluene and chloroform as solvents, the composition of polymerization with different monomer ratio was tested in elementary analysis. With caculation methed of Rate of slop/intercept the reactivity ratios are r1 =0, r2 =0.5 and r1 =0, r2 =0.39 respectively.
