| Abstract: | Two concentrated emulsions in water were prepared: one from butyl methacrylate(BMA) and other from styrene(St). After the concentrated emulsions were partially pre polymerized, they were mixed and subjected to complete polymerization. Because monomers diffused across water into cells each other during the subsequent polymerization, two types of quasi block copolymers were generated. Such quasi block copolymer as compatibilizers existed at the interfaces and decreased the interfacial tension. The compatibilization made the domain of the dispersed phase finer and the interface between the matrix and the toughener smeared and thus improved the combination of the two components. As a result, auto compatible blend, possessing excellent toughness, was obtained. |
