Elastomeric copolymer compositions and articles made therewith

A dip formed elastomer article comprising a thin film having a thickness of from about 0.03 to about 1.0 millimeters, the film being formed of an elastomer comprising

• a block copolymer consisting essentially of a single S-EB-S block copolymer, the S-EB-S block copolymer having at least about 15 weight percent of styrene end blocks, and wherein the weight average molecular weight of the styrene end blocks is at least about 7,000 Daltons and the weight average molecular weight of ethylene-butylene midblocks is at least about 60,000 Daltons, and wherein the weight average molecular weight of the S-EB-S block copolymer is less than about 175,000 Daltons, and
• a plasticizer in an amount sufficient to provide tactility in the dip formed article.
