Block copolymer composition and pressure sensitive adhesive composition.

摘要

A block copolymer composition comprising 20-90 wt.% of at least one block copolymer selected from the group consisting of block copolymers represented by the general formula (S-B-I)n-X and block copolymers represented by the general formula (S-I-B)n-X, and 80-10 wt.% of at least one block copolymer selected from the group consisting of block copolymers represented by the general formula S-B-I and block copolymers represented by the general formula S-I-B, and a pressure sensitive adhesive composition comprising, as a base polymer, the block copolymer composition are provided
