Claim Text:
1. A cold flow resistant composition comprising: (a) a diene rubber; and (b) a conjugated diene monovinylarene block copolymer, the conjugated diene monovinylarene block copolymer having from about 50 to about 95 wt. % monovinylarene monomer content, based on the total weight of the block copolymer; wherein: a solution viscosity of the composition is less than a solution viscosity of the diene rubber; a cold flow of the composition is less than a cold flow of the diene rubber; the composition contains less than 1 wt. % solvent; and the composition comprises from about 15 to about 30 wt. % of the conjugated diene monovinylarene block copolymer, based on the total weight of the composition.
