    摘要: Syndiotactic polystyrene can be impact-modified by a blend of (a) polystyrene-hydrogenated polybutadiene block copolymers and (b) one or more core/shell modifiers based on a lightly or non-crosslinked rubber core, and with at least one shell or intermediate shell stage which is predominantly polystyrene, to produce a material of higher impact strength than the better value of either additive singly at the same total impact modifier level.
