Abstract

The present invention provides transparent resin composition exhibiting weathering resistance and heat resistance, and a molded product thereof. A transparent, highly heat resistant resin composition can be obtained by a resin composition comprising an aromatic vinyl-(meth)acrylic acid ester-unsaturated dicarboxylic acid anhydride copolymer (A) in which the amount of residual unsaturated dicarboxylic acid anhydride monomer is at most 100 ppm, and an ultraviolet absorber (B), wherein the content of ultraviolet absorber is 0.03-1.0 mass%. In addition to the (A) and (B), the composition may also comprise methacrylic resin (C).

Description

【Technical field】 [0001] The present invention relates to a transparent high heat-resistant resin composition excellent in weather resistance. 【Background technique】 [0002] Transparent resins such as methacrylic resins and polystyrene are used in various applications such as home appliance parts, automotive parts, food packaging containers, building materials, and miscellaneous goods. In addition, taking advantage of its excellent transparency, it is also used as an optical component of liquid crystal display, and is widely used in optical films, diffusion plates, light guide plates, etc. Methacrylic resin and polystyrene have problems such as good optical properties such as transparency but low heat resistance, and are used in limited applications. Techniques for improving heat resistance include the following.
