    摘要: A blend of a modified thermoplastic block polymer of a conjugated diene and an alkenyl arene with an extender resin compatible with the conjugated diene block is described herein. The block copolymer is first selectively hydrogenated and thereafter modified by grafting carboxyl functional groups primarily in the alkenyl arene blocks.
