Patent ID: 7193014

Claim:
A composition, comprising: (i) from about 25 parts by weight to about 95 parts by weight of a monovinylarene-conjugated diene coupled block copolymer comprising at least one tapered block, having a blocky monovinylarene content of less than 90 wt % of total monovinylarene units, and comprising a terminal monovinylarene block having a molecular weight of less than 60,000 g/mol; (ii) from about 5 parts by weight to about 75 parts by weight of a monovinylarene-alkyl (meth)acrylate copolymer, comprising (ii-a) monovinylarene units and (ii-b) at least one of ethyl acrylate units, propyl acrylate units, butyl acrylate units, pentyl acrylate units, or hexyl acrylate units; and (iii) about 0.1 parts by weight to about 20 parts by weight of a macromolecular compound wherein all materials copolymerized in said macromolecular compound result in a monovinylarene-conjugated diene rubber.
