Syndiotactic polystyrene copolymer resin composition having macromonomer for improving impact strength |
摘要 |
<p>Disclosed is a syndiotactic polystyrene copolymer resin composition with high impact strength, which comprises: (A) 1-99 weight % of a syndiotactic polystyrene copolymer which is polymerized from at least one macromonomer having an active polymerization group at its end and at least one styrene monomer; and (B) correspondingly 99-1 weight % of at least one rubber phase resin and/or at least one thermoplastic resin. Optionally, the (B) component further comprises at least one polar group-containing rubber phase resin and/or at least one rubber phase resin of a core/shell structure in which a core moiety is of a rubber phase, being coated with a shell moiety polymerized from styrene monomers or styrene-containing vinyl monomers. The macromonomer with a terminal polymerization-active group makes the polystyrene resin compatible with rubber phase resins and thermoplastic resins, thereby bringing about a great improvement in the impact strength of the polystyrene resin composition. Also, the macromonomer itself makes a contribution to the improvement in the impact strength of the polystyrene resin.</p> |
