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。
The reaction of 7-methylene-1,4,6-trioxaspiro [4,4] nonane with electron donor vinyl acetate (VA), electron acceptor methyl acrylate (MA) and acrylonitrile AN) free radical copolymerization reaction. The copolymers were characterized by IR, 1H NMR and GC spectra. The structure of the copolymers was confirmed. The copolymers were well copolymerized with VA. The composition ratio and yield of the copolymers were affected by temperature. When copolymerized with MA, AN, the feed ratio affects the copolymer yield without affecting the copolymer composition ratio. By studying CT complexes, the mechanism of copolymerization was discussed. Influence on the copolymerization activity of the substituent, copolymer structure made a preliminary study.
