HYDROGENATED BLOCK COPOLYMER AND COMPOSITION THEREOF

摘要

An object of the present invention is to provide a hydrogenated block copolymer having excellent flexibility, heat resistance, abrasion resistance and surface texture (no stickiness, oil bleeding etc.) and good processability, and a composition thereof. The present invention provides a hydrogenated block copolymer that has therein at least one of each of a vinyl aromatic compound polymer block A, a hydrogenated polymer block B of a random copolymer comprising a conjugated diene and a vinyl aromatic compound, and a hydrogenated polymer block C of a conjugated diene polymer having a vinyl bond content of not less than 30%, the hydrogenated block copolymer having a vinyl aromatic compound content of more than 50 wt% and less than 95 wt%, and a composition containing the hydrogenated block copolymer.
