CRUMB OF BLOCK COPOLYMER AND ADHESIVE COMPOSITION

摘要

Provided is a crumb of a block copolymer which has excellent transportability and is capable of forming an adhesive composition that has excellent solubility, low melt viscosity characteristics and low odor characteristics, with an excellent balance among these characteristics, in cases where the crumb of a block copolymer is used in the adhesive composition. The present invention relates to a crumb of a block copolymer, which contains a polymer block mainly composed of at least one vinyl aromatic hydrocarbon monomer unit and a polymer block mainly composed of at least one conjugated diene compound monomer unit and has a weight average molecular weight of 20,000-1,000,000, while having a specific surface area, a cumulative pore volume of pores having pore radii of 1-100 μm and an average pore radius respectively within specific ranges.
