Abstract
Provided is a styrene resin composition including α-methyl styrene, acrylonitrile and vinyl imidazole, and having an improved conversion rate while maintaining excellent mechanical and chemical properties, a styrene resin composition including the same, and a styrene resin molded product manufactured therefrom. Accordingly, the heat-resistant styrene copolymer is effective in improving a conversion rate without deformation and mechanical and chemical property decline of the material itself, and as a result, commercialization may be readily accomplished due to enhanced productivity. In addition, the styrene resin molded product manufactured from the styrene resin composition according to the present invention includes the heat-resistant styrene copolymer as a matrix copolymer, and therefore, has excellent impact strength, tensile strength, tensile elongation and flowability while having high heat resistance.
