英文摘要	Polybutadiene-g-poly(styrene-co-acrylonitrile) (pb-g-san) impact modifiers with different polybutadiene (pb)/poly(styrene-co-acrylonitrile) (san) ratios ranging from 20.5/79.5 to 82.7/17.3 were synthesized by seeded emulsion polymerization. acrylonitrile-butadiene-styrene (abs) blends with a constant rubber concentration of 15 wt % were prepared by the blending of these pb-g-san copolymers and san resin. the influence of the pb/san ratio in the pb-g-san impact modifier on the mechanical behavior and phase morphology of abs blends was investigated. the mechanical tests showed that the impact strength and yield strength of the abs blends had their maximum values as the pb/san ratio in the pb-g-san copolymer increased. a dynamic mechanical analysis of the abs blends showed that the glass-transition temperature of the rubbery phase shifted to a lower temperature, the maximum loss peak height of the rubbery phase increased and then decreased, and the storage modulus of the abs blends increased with an increase in the pb/san ratio in the pb-g-san impact modifier. the morphological results of the abs blends showed that the dispersion of rubber particle in the matrix and its internal structure were influenced by the pb/san ratio in the pb-g-san impact modifiers.
