Abstract:
A main object of the present disclosure is to provide a block copolymer composition that allows a hot melt adhesive composition having excellent hot melt properties and heat resistance stability to be obtained. The object is achieved by providing a block copolymer composition comprising a block copolymer A including an Ar 1 -D 1  diblock as a branched chain, the block copolymer A represented by the following general formula (I), characterized in that: a molecular weight distribution (Mw/Mn) of the block copolymer A is 1.20 or less; a content of the block copolymer A in the block copolymer composition is 10% by mass or more; a content of a block copolymer B corresponding to an Ar 2 -D 2  diblock represented by the following general formula (II), in the block copolymer composition is 60% by mass or less, and a molecular weight distribution (Mw/Mn) of the block copolymer B is 1.15 or less; a content of an aromatic monovinyl monomer unit in the block copolymer composition is in a range of 12% by mass to 30% by mass; a weight average molecular weight (Mw) of the entire block copolymer composition is in a range of 300000 to 800000; and a melt index (G condition) of the entire block copolymer composition is in a range of 2 g/10 min to 20 g/10 min.

Claim (Index 2):
The block copolymer composition according to  claim 1 , wherein the multifunctional coupling agent is a compound including 2 or more of radical polymerizable groups in a molecular.
