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 DEG 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 DEG 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. |
