【発明の名称】エラストマー共重合体組成物及びかかる組成物より製造した物品
Document Type and Number:
Japanese Patent JP2001505238
Kind Code:
A
Abstract:
An elastomeric composition includes a single S-EB-S block copolymer having at least about 15 weight percent of styrene end blocks, 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 a plasticizer in an amount sufficient to provide tactility in products made from the composition. To prepare articles such as medical film protective devices, the elastomeric composition is dissolved in a sufficient amount of a solvent to permit dip forming. A form having the shape of the desired product is dipped into the solution to build up a film of the elastomeric composition on the form. The dip-formed elastomeric films are free of pinholes and resistant to oxidative and ozone attack. The films are particularly suitable for use in products such as examination, surgical, and industrial gloves and condoms.
