Abstract
An elastomeric article is formed from a blend of nitrile rubber and polychloroprene rubber. The elastomeric article can be a glove, such as a medical exam glove. The elastomeric article is softer than a conventional nitrile elastomeric article. The elastomeric article is formed from a blended rubber latex emulsion of nitrile and polychloroprene. The blended rubber latex emulsion may be free of sulfur and vulcanization accelerators.
