Abstract
PURPOSE: A composition that is made by adding a modified block copolymer with dicarboxylic or other groups bound, to another specific block copolymer having conjugate diene blocks on chain terminals, thus having improved mechanical properties such as tensile strength or hardness, adhesion, and other characteristics.
CONSTITUTION: (A) An aromatic vinyl compound-conjugate diene block copolymer having polymer blocks mainly composed of comjugate diene on chain terminals of formulaIWIV (A is polymer block mainly consisting of aromatic vinyl compound; B is polymer block mainly consisting of conjugate diene; X is residual group of a coupling agent with 2 or more functional groups; n is 1 or more integer; m is 2 or more integer; p is 1 or more integer) is combined with (B) a modified block copolymer prepared by introducing dicarboxylic groups or its derivatives into an aromatic vinyl compound-conjugate diene block copolymer to give the objective composition.
