PURPOSE:To obtain the thermoplastic resin-composition excellent in heat resistance, light exposure properties and chemical resistance by injection-molding specified hydrogenated norbornane resin (component A), rubber polymer and 1 or the thermoplastic resin except the component A under specified condition. CONSTITUTION:The hydrogenated norbornane resin (component A) made by hydrogenating the polymer obtained by meta-polymerizing at least one kind of norbornane derivative expressed by formula I shown thesis or an unsaturated cyclic compound capable of copolymerizing with the derivative, rubber polymer and/or the thermoplastic resin (component B) except the component A, are prepared. The thermoplastic resin-composition containing the component A of 50-100wt.% and the component B of 50-0wt.% is injection-molded in the condition of a mold temperature of (Tg-70 deg.C)-(Tg+10 deg.C)(Tg: glass transition temperature), a resin-temperature of 280-360 deg.C and a rate of strain of 5X10<2>-2X10<4>sec<-1>. In the formula, m is zero or 1, and A, B are hydrogen atom or the terminal of prime number 1-10 or hydrogen radical. |
