Abstract:
A process for the preparation of elastomeric articles, comprising the steps of:furnishing a liquid solution 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; a plasticizer in an amount sufficient to provide tactility in dip formed products made from the composition; and a solvent in an amount sufficient to form a stable solution of the block copolymer component and the plasticizer and to permit dip forming of products from the liquid solution; dipping a form into the solution and withdrawing the form from the solution; and evaporating the solvent from the film on the form, leaving a coherent extensible film on the form.
