六(甲氧基甲基)三聚氰胺(HMMM)-二缩三乙二醇(T_3EG)和二缩三乙二醇二甲基丙烯酸酯(T_3EGMA)的混合体系加入潜酸催化剂后,在较高温度下可同时进行缩聚和自由基聚合并表现出协同效应.在这一混合聚合体系中HM-MM不仅是交联剂,而且是体系中活泼亚甲基氧化为过氧化氢物的催化剂,由潜酸催化剂分解出的酸是缩聚的催化剂,也是过氧化氢物分解为自由基的催化剂,生成的自由基可引发T_3EGMA聚合.有关凝胶时间实验,吸氧实验和活性氧测定的结果支持上述论断.
After the mixed system of hexamethoxymethane (HMMM) -triethylene glycol (T_3EG) and triethylene glycol dimethacrylate (T_3EGMA) was added to the latent acid catalyst, Under the simultaneous polycondensation and free radical polymerization and show a synergistic effect.In this mixed polymerization system, HM-MM is not only a cross-linking agent, but also a catalyst for active methylene oxide to hydrogen peroxide in the system, Acid decomposition of the acid catalyst is a polycondensation catalyst, but also the decomposition of hydrogen peroxide into free radical catalyst, the generated free radicals can trigger T_3EGMA polymerization. The gel time experiments, oxygen experiments and reactive oxygen determination results support the above assertion .
