1.对环化聚合的反应机构作了动力学探讨,认为除文献上所考虑的单分子环化机构外,还应当考虑双分子环化机构。并得到聚合组分方程为线性方程; 2.通过二丙烯基丙二酸二乙酯(DDM)及邻苯二甲酸二丙烯酯(DAP)的环化聚合研究,以及对文献上二甲基丙烯酸二缩乙二醇酯(DDMA)聚合数据的处理,验证了所得的聚合组分方程。在DDM聚合时按双分子环化机构反应速度比按单分子环化至少快16.3倍;在DAP及DDMA聚合时双分子环化机构与单分子环化机构都不容忽视。
1. A kinetic study of the cyclization polymerization reaction mechanism is considered, in addition to the literature considered monolayer cyclization mechanism, should also consider the bimolecular cyclization mechanism. And the equation of the polymerization component is obtained as a linear equation. 2. The cyclization polymerization of di-propenyl diethyl malonate (DDM) and diallyl phthalate (DAP), as well as the literature review of dimethacrylic acid Polyethylene glycol dimethacrylate (DDMA) polymerization data were processed to verify the resulting equation of the polymerization component. In DDM polymerization, the reaction speed of bimolecular cyclization mechanism is at least 16.3 times faster than that of single-molecule cyclization; in the polymerization of DAP and DDMA, the bimolecular cyclization mechanism and the monomolecular cyclization mechanism can not be ignored.
