Title:
HEAT RESISTANT STYRENE-BASED COPOLYMER AND STYRENE-BASED RESIN COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2015/163609
Kind Code:
A1
Abstract:
The present invention relates to: a heat resistant styrene-based copolymer having an improved conversion rate while maintaining excellent mechanical and chemical properties, and comprising α-methylstyrene, acrylonitrile and vinylimidazole; a styrene-based resin composition containing the same; and a styrene-based resin molded product prepared therefrom. The heat resistant styrene-based copolymer according to the present invention has an effect of having improved conversion rate without the modification of a material itself and the deterioration of mechanical and chemical properties, and thus productivity is improved, thereby facilitating commercialization. In addition, a styrene-based resin molded product prepared from the styrene-based resin composition according to the present invention contains the heat resistant styrene-based copolymer as a matrix copolymer, and thus has excellent impact strength, tensile strength, tensile elongation and flowability while having high heat resistance.
