  • Readily donned, powder-free elastomeric article
    Publication number: 20050031817
    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.
