Block copolymers are provided which exhibit reduced sensitivity to organic solvents which comprise block copolymers of at least one elastomeric conjugated diene polymer block, block copolymerized with at least two monovinyl arene polymer blocks, all chains also containing either polyethylene or butadiene blocks, this latter block at least being hydrogenated to an extent sufficient to reduce the original double bonds by at least about 80 percent.
