The preparation of graft copolymers of styrene, acrylonitrile and n-butyl acrylate on to a polybutadiene rubber by emulsion polymerization and up to high degrees of conversion are described and investigated theoretically. The resulting graft copolymers have a higher styrene content and a lower acrylonitrile content than predicted by theory, whereas the n-butyl acrylate has the expected content. Impact and notched impact resistances, bending and tensile strengths, ball-puncture resistance, Vicat softening temperature and glass transition temperatures of the graft copolymers have been measured and are discussed.
