IMPACT-RESISTANT VINYLAROMATIC HYDROCARBON RESIN |
摘要 |
An impact-resistant vinyl aromatic hydrocarbon resin, the hydrocarbon resin being produced by radical polymerization of 75 to 98 parts by mass of a vinyl aromatic hydrocarbon monomer (A-1) or a mixture of a vinyl aromatic hydrocarbon monomer and a monomer copolymerizable therewith (A-2) and 2 to 25 parts by mass of amodifiedblock copolymer (B), wherein the component (B) comprises a base block copolymer (B-1) comprising conjugated diene monomer units and vinyl aromatic hydrocarbon monomer units and containing at least one polymer block of vinyl aromatic hydrocarbon monomer units (H), and a modifier group bonded thereto (B-2); and the component (B) has the following characteristics: (i) the content of the vinyl aromatic hydrocarbon monomer units is 12 to 50 mass%; (ii) the content of the polymer block (H) is 12 to 45 mass%; and (iii) the polymer block ratio (the mass% of the polymer block (H) based on the total mass of vinyl aromatic hydrocarbon monomer units contained in (B)) is more than 50 mass%. |
