摘要： 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.

Abstract: The morphology and process of phase-separation of toughening epoxy resin with epoxy-functional poly(n-butyl acrylate) (ETPnBA) and carboxy-functional poly (n-butyl acrylate) (CTPnBA) rubbers were studied by the optical microscope. The effect of curing conditions and prereact time of rubber and epoxy resin on the phase-separation were investigated. The control of the phase-separation and the mechanism of the phase-separation of the modified epoxy resin (by ETPnBA and CTPnBA rubbers) were discussed.
