BLOCK COPOLYMER COMPOSITION, MOLDING MATERIAL, RESIN COMPOSITION, AND MOLDED ARTICLE

摘要

A block copolymer composition composed of a polymer (a) containing a vinyl aromatic monomer unit in an amount of more than 95% by mass and 100% by mass or less and a conjugated diene monomer unit in an amount of 0% by mass or more and less than 5% by mass and a block copolymer (b) containing a vinyl aromatic monomer unit in an amount of 15 to 50% by mass inclusive and a conjugated diene monomer unit in an amount of 50 to 85% by mass inclusive, wherein the ratio of the content of the polymer (a) to the content of the block copolymer (b) (i.e., (a)/(b)) is 70/30 to 30/70 by mass.
