摘要： Rubber particles comprising a hydrogenated block copolymer of a conjugated diene and a vinyl aromatic compound, said particles having a glass transition temperature of -30.degree. C. or less, a gel content of at least 10%, an average particle size of 0.01 to 5.0 .mu.m, and a micro-phase separating structure having hard segments and soft segments, wherein hard segments and soft segments are alternately laminated together in the form of concentric multilayers, are useful in reinforcing resin compositions. A particular reinforced resin composition is comprised of a matrix resin having a glass transition temperature of at least 0.degree. C. and 1 to 60% by weight of the above defined rubber particles dispersed in the matrix resin. The rubber particles have a great reinforcing effect on the matrix resin and resin compositions reinforced with these rubber particles are characterized with superior weather resistance, heat stability and impact resistance properties.

摘要： A process for producing a copolymer by continuously copolymerizing in a solution monomers comprising 40 to 95% by weight of an aromatic vinyl compound and 5 to 60% by weight of a vinyl cyanide compound, and further 0 to 30% by weight of a vinyl compound copolymerizable with the aromatic vinyl compound and vinyl cyanide compound, wherein 10 to 100 parts by weight of a solvent containing not less than 40% by weight of an alcohol is used as the polymerization solvent based on 100 parts by weight of the total amount of the monomers. According to the process, attachment of a gel-like polymer onto the polymerization vessel or device can be prevented. The copolymer is useful as a thermoplastic resin for various molded articles including electrical parts for domestic uses, automobile parts and commodity goods.
