(Modified) hydrogenated diene block copolymer and composition comprising the same |
摘要 |
A hydrogenated diene block copolymer having a polystyrene-reduced number-average molecular weight of 50,000-600,000 which is a hydrogenation product of an (A)-(B) block copolymer in which (A) means an alkenyl aromatic compound polymer block and (B) means a conjugated diene homopolymer block wherein the vinyl content of the conjugated diene portion is more than 60%, or an alkenyl aromatic compound-conjugated diene random copolymer block wherein the vinyl content of the conjugated diene portion is 15% or more, an (A)-(B)-(C) block copolymer in which (A) and (B) are as defined above and (C) means an alkenyl aromatic compound-conjugated diene copolymer tapered block wherein the proportion of the alkenyl aromatic compound increases gradually, or an (A)-(B)-(A) block copolymer in which (A) and (B) are as defined above. Said hydrogenated diene block copolymer is useful as a modifier for polar resins, non-polar resins or both of them.
