用光学显微镜观察环氧官能团聚丙烯酸丁酯橡胶(ETPnBA)和羧基官能团聚丙烯酸丁酯橡胶(CTPnBA)增韧环氧树脂相分离的形态,研究固化条件和橡胶与环氧树脂的预反应程度对相分离的影响,讨论了体系相分离的控制.
The morphology of epoxy resin toughened by epoxy functional polybutyl acrylate rubber (ETPnBA) and carboxyl functional polybutyl acrylate rubber (CTPnBA) was observed by light microscopy. The curing conditions and the degree of pre-reaction between rubber and epoxy resin The influence of phase separation, the control of phase separation is discussed.
