Abstract
Provided is a cross-linkable polymer composition comprising a hydrogenated block copolymer composition comprising a hydrogenated block copolymer A represented by General Formula (A) and a hydrogenated block copolymer B represented by General Formula (B) in a specific weight ratio (A/B) and having a hydrogenation ratio of olefins of 10 to 100%; and a polyolefin thermoplastic resin C in a specific ratio (C/(A+B)); and further comprising a cross-linking agent.
Claims15
A cross-linkable polymer composition comprising:
- a hydrogenated block copolymer composition comprising a hydrogenated block copolymer A represented by General Formula (A) and a hydrogenated block copolymer B represented by General Formula (B);
- a polyolefin thermoplastic resin C;
- and
- a cross-linking agent,
- wherein the hydrogenation ratio of olefins in the polymer components contained in the hydrogenated block copolymer composition is 10 to 100%,
- the weight ratio (A/B) of the hydrogenated block copolymer A to the hydrogenated block copolymer B in the hydrogenated block copolymer composition is 10/90 to 80/20, and
- the weight ratio (C/(A+B)) of the content of the polyolefin thermoplastic resin C to the total content of the hydrogenated block copolymer A and the hydrogenated block copolymer B is 5/95 to 80/20:
- where in General Formulae (A) and (B) above, Ar1a, Ar2a, Ar1b, and Ar2b are each an aromatic vinyl polymer block, HDa and HDb are each a hydrogenated polymer block of a conjugated diene polymer, the ratio (Mw(Ar2a)/Mw(Ar1a)) of the weight average molecular weight of Ar2a (Mw(Ar2a)) to the weight average molecular weight of Ar1a (Mw(Ar1a)) is 3.0 to 20, and the ratio (Mw(Ar2b)/Mw(Ar1b)) of the weight average molecular weight of Ar2b (Mw(Ar2b)) to the weight average molecular weight of Ar1b (Mw(Ar1b)) is 0.95 to 1.05.
