Patent ID: 8048362

Claim:
A molded article, obtained by molding a resin composition into a shape and thereafter exposing the shape to an active energy ray to crosslink the resin composition, wherein the resin composition comprises an addition polymerization block copolymer (I) and a polyolefin resin (II), wherein: the addition polymerization block copolymer (I) is at least one copolymer selected from the group consisting of a block copolymer comprising at least one polymer block A and at least one polymer block B and a hydrogenated product thereof; the polymer block A comprises an aromatic vinyl compound unit comprising at least 1% by mass of an alkylstyrene-derived structural unit (a) in which at least one alkyl group having 1 to 8 carbon atoms is bound to a benzene ring; and the polymer block B comprises a conjugated diene compound unit, wherein 70% or more of the carbon-carbon double bonds of the polymer block B are hydrogenated; and at least the moiety of polymer block A can undergo crosslinking upon exposure to an active energy ray, wherein the polyolefin resin (II) is at least one polyolefin selected from the group consisting of a high density polyethylene, a middle density polyethylene, a low density polyethylene and an ethylene-α-olefin copolymer, and the addition polymerization block copolymer (I) and the polyolefin resin (II) are present in a mass ratio of 90/10 to 1/99.
