HYDROGENATED BLOCK COPOLYMER, RESIN COMPOSITION COMPRISING THE HYDROGENATED BLOCK COPOLYMER, AND CROSSLINKED PRODUCT AND CROSSLINKED FOAMED PRODUCT THEREOF

摘要

Provided is a hydrogenated block copolymer for preparing a foam excellent in tear strength, compression set resistance, low impact resilience, and abrasion resistance. More specifically, provided is a hydrogenated block copolymer comprising a vinyl aromatic compound and a conjugated diene, wherein: (a) the vinyl aromatic unit content is greater than 35 wt. % and not greater than 90 wt. %, (b) the vinyl aromatic polymer block content is not greater than 40 wt. %, (c) the weight average molecular weight is from 5x104 to 100x104, and (d) the hydrogenation ratio of double bonds derived from the conjugated diene is less than 70%.
