HYDROGENATED BLOCK COPOLYMER PELLET, ADHESIVE COMPOSITION, AND SURFACE PROTECTION FILM

摘要

A hydrogenated block copolymer pellet having:
100 parts by mass of a pellet molded product of hydrogenated block copolymer A and0.01 to 1.5 parts by mass of an antiblocking agent of polyethylene-based powder B, whereinthe hydrogenated block copolymer A has a polymeric block a mainly having at least one vinyl aromatic monomer unit and polymeric block b mainly having at least one conjugated diene monomer unit, in whicha total content of the 1,2-bond content and the 3,4-bond content in the hydrogenated block copolymer A before hydrogenation is less than 40 mol %, based on the total binding amount of the conjugated diene monomer unit.
