THERMOPLASTIC ELASTOMER COMPOSITION AND MOLDED BODY |
摘要 |
The thermoplastic elastomer composition of the present invention is a thermoplastic elastomer composition including a hydrogenated block copolymer (A) and a softening agent (B), the hydrogenated block copolymer (A) being a hydrogenated product of a block copolymer including a polymer block (a) composed of a constitutional unit derived from an aromatic vinyl compound and a polymer block (b) containing 1 to 100% by mass of a constitutional unit (b1) derived from farnesene and 99 to 0% by mass of a constitutional unit (b2) derived from a conjugated diene other than farnesene; a mass ratio of the polymer block (a) and the polymer block (b) [(a)/(b)] being 1/99 to 70/30; 50 mol% or more of carbon-carbon double bonds in the polymer block (b) being hydrogenated; and a content of the softening agent (B) being 20 to 2,000 parts by mass on the basis of 100 parts by mass of the hydrogenated block copolymer (A). |
