| 摘 要： | 叙述了7-亚甲基-1,4,6-三氧螺4,4]壬烷与给电子单体醋酸乙烯酯(VA)、受电子单体丙烯酸甲酯(MA)和丙烯腈(AN)的自由基共聚合反应。分析共聚物的红外、核磁共振氢谱和碳谱,确定了共聚物的结构,该螺环单体能与VA很好共聚,共聚物的组成比和产率受温度的影响。当与MA、AN共聚时,投料比影响共聚物产率,而不影响共聚物组成比。通过对CT络合物研究,探讨了共聚反应机理。对取代基影响共聚活性,共聚物结构作了初步研究。

| Abstract: | This paper describes the copolymerization of 7-methylene-2-methyl(or n-butyl)-trioxaspiro (4,4) nonane MTN) with vinyl acetate (VA), ormethyl acrylate (MA), or acrylonitrile (AN). The structure of copolymers isidentified by nalyses of IR, ~1H and ~13C NMR spectra of copolymers. Theresults indicate that the copolyerization of MTN and VA akes place, therepeating units and their relative amount affected by copolymerization tempe-rature. In the opolymerization of MTN with MA, or AN, the feed composi-tion affects the yields of the copolymers, but does not ffect he composition of copolymeys. The CT complex may participate the copolymerization.The copolymerization echanism, and the effect of substituents on thereactive activity of MTN, and the structure of copolymers are iscussed. |
