Claims14
A thermoplastic resin composition comprising:
- (A) 100 parts by mass of a thermoplastic resin;
- (B) 0.05 to 5 parts by mass of one or more selected from the group consisting of an unsaturated carboxylic acid and a derivative of an unsaturated carboxylic acid;
- and
- (C) 0.01 to 3 parts by mass of an organic peroxide,
- said thermoplastic resin (A) comprising:
- (a1) 10 to 90% by mass of a cyclic polyolefin-based polymer having a glass transition temperature of 70 to 160° C.;
- and
- (a2) 90 to 10% by mass of one or more selected from the group consisting of a copolymer of an aromatic vinyl compound and a conjugated diene compound and a hydrogenated product thereof except for a hydrogenated product of a block copolymer of a polymer block mainly composed of an aromatic vinyl compound and a random copolymer block composed of a conjugated diene compound and an aromatic vinyl compound,
- wherein the component (a2) is at least one selected from the group consisting of a styrene-ethylene-propylene copolymer (SEP), a styrene-ethylene-butene-styrene copolymer (SEBS), a styrene-ethylene-propylene-styrene copolymer (SEPS), a styrene-ethylene-ethylene-propylene-styrene copolymer (SEEPS) and a hydrogenated product thereof,
- wherein the total of the components (a1) and (a2) is 100% by mass, and
- the component (a1) is a copolymer of a cyclic olefin and an a-olefin having 2 to 8 carbon atoms.
