| 摘要 |
Provided is a thermoplastic polymer composition containing an aromatic vinyl-based block copolymer (a-1) having a number average molecular weight of 30,000 to 200,000, the aromatic vinyl-based block copolymer containing a polymer block F containing a structural unit derived from an aromatic vinyl-based monomer as a main component and a hydrogenated or non-hydrogenated polymer block G containing a structural unit derived from a conjugated diene monomer or an isobutylene monomer as a main component; an acrylic polymer (a-2); an olefin-based polymer containing polar groups (a-3); and a softening agent (a-4), at the proportions that satisfy the following Expressions (1) to (3):;0.05≦W(a-2)/W(a-1)≦9 (1);0.1<W(a-3)/(W(a-1)+W(a-2)+W(a-3)+W(a-4))≦0.9 (2), and;0≦W(a-4)/(W(a-1)+W(a-2)+W(a-3)+W(a-4))≦0.5 (3);wherein W(a-1), W(a-2), W(a-3) and W(a- 4) represent the contents (on a mass basis) of the aromatic vinyl-based block copolymer (a-1), acrylic polymer (a-2), olefin-based polymer containing polar groups (a-3) and softening agent (a-4), respectively, in the thermoplastic polymer composition. |

1. A thermoplastic polymer composition comprising:
an aromatic vinyl-based block copolymer (a-1) having a number average molecular weight of 30,000 to 200,000, the aromatic vinyl based block copolymer (a-1) containing a polymer block F containing a structural unit derived from an aromatic vinyl-based monomer as a main component, and a hydrogenated or non-hydrogenated polymer block G containing a structural unit derived from a conjugated diene monomer or an isobutylene monomer as a main component; an acrylic polymer (a-2); an olefin-based polymer containing polar groups (a-3); and a softening agent (a-4),at the proportions satisfying the following Expressions (1) to (3):
0.05≦W(a-2)/W(a-1)≦9 (1) 0.1<W(a-3)/(W(a-1)+W(a-2)+W(a-3)+W(a-4))≦0.9 (2), and 0≦W(a-4)/(W(a-1)+W(a-2)+W(a-3)+W(a-4))≦0.5 (3)wherein W(a-1), W(a-2), W(a-3) and W(a-4) represent the contents (on a mass basis) of the aromatic vinyl-based block copolymer (a-1), acrylic polymer (a-2), olefin-based polymer containing polar groups (a-3) and softening agent (a-4), respectively, in the thermoplastic polymer composition. |
