Styrene resin composition low surface gloss and low surface brightness laminar element and composite article manufactured from the same

摘要

Styrene resin composition low surface gloss comprising: (A) 80 to 99.9% by weight of a basic resin comprising (a) polymer-modified styrene rubber and (b) a styrene unmodified gum ; (B) 0.1-20% by weight of a syndiotactic polystyrene having a melting point range 260 to 280 ° C as matting agent; and (C) a hydrogenated styrene block copolymer comprising styrene and butadiene rubber block block as a compatibilizer in an amount of 0.1-20% by weight to the total weight of the styrene resin low surface gloss comprising (A ) the base resin and (B) the matting agent; wherein the modified styrene polymer rubber (a) contains 5 to 30% by weight of a gum, 40-90% by weight of a styrene monomer and 5-30% by weight of an ethylenically unsaturated compound and styrene unmodified rubber (b) is prepared by copolymerizing a styrene monomer and an ethylenically unsaturated compound.
