摘要
The present invention relates to a low surface gloss styrene resin composition. The composition of the present invention is composed of (A) 80-99.9 weight % of the basic resin comprising rubber-modified styrene resin and (B) 0.1-20 weight % of syndiotactic polystyrene, the matting agent. The composition also includes (C) hydrogenated styrene block copolymer comprising styrene block and butadiene rubber block as a compatibilizer by 0.1-20 weight % for the total weight of the low surface gloss styrene resin composed of (A) the basic resin and (B) the matting agent and additionally includes (D) a plasticizer by 0.1-30 weight %. The composition of the present invention has excellent weatherability and impact-resistance in addition to the low surface gloss properties, so that it can be applied in various products, particularly exterior products for structures such as sidings and window frames, etc.
