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.
