摘要: 六甲氧基甲基三聚氰胺(HMMM)-多元醇-丙烯酸酯-酸催化剂的混合体系在较高温度下同时进行缩聚和自由基聚合并表现出协同效应。DSC研究结果表明,丙烯酸酯在HMMM和酸的催化作用下可在较低温度下发生自由基聚合反应,并把反应释放出来的大量的热量有效地传递给缩聚反应,满足缩聚反应吸热的要求,从而节省固化所需要的能量。为了提高储存稳定性,本文以潜酸催化剂作为酸的来源,对该混杂聚合体系进行了研究,仍有明显的热互补效应。

Abstract: The hybrid polymerization of hexamethoxymethyl melamine (HMMM)-polyol-acrylate and acidinvolves the condensation reactions of HMMM-polyol and the free radical polymerization of acrylate.DSC investigation shows that catalyzed by HMMM-polyol and acid, the free radical poymerization of acrylatetakes place at a lower temperature and the released energy can be transferred to the endothermic condensa-tion reactions of HMMM efficiently, saving much energy needed for the curing.To lengthen the shelf timeof the formulation, we have also investigated the hybrid poymerization system in which the latent acid cat-alyst was used as the source of acid, and observed the energy compensation effect, too.

Key words: Hybrid Polymerization, Energy compensation effect, Hexamethoxymethyl melamine, Acry-late, Latent acid catalyst
