Abstract

An elastomeric article such as a glove includes a substrate body made of an styrene-ethylene-butylene-styrene block copolymer, and a donning layer overlying at least one side of the substrate body. The donning layer is formed of 1,2 polybutadiene, preferably syndiotactic 1,2 polybutadiene, or a chlorinated mid block unsaturated block copolymer. Optionally, a surfactant layer is present over the donning layer to further improve the donning characteristics. The surfactant layer is preferably an alkyl dimethylbenzyl quaternary, an alkyl trimethyl quaternary, a dialkyl dimethyl quaternary, sodium lauryl sulfate, or pyridinium chloride.

Claims

1. A multi-layered elastomeric article, comprising:

a hollow substrate body including a layer made of an elastomeric material, said hollow substrate body including an inside surface and an outside surface; and

a donning layer overlying the inside surface of the hollow substrate body, the donning layer comprising 1,2 polybutadiene.

2. The elastomeric article of claim 1, wherein the elastomeric material of the substrate body comprises a mid block saturated styrene block copolymer.
