Abstract
A polychloroprene article comprises a polymer which is more readily chlorinatable that polychloroprene. A method of making the article comprises forming the article from an aqueous dispersion or solution of polychloroprene, characterized in that one or more polymers which are more readily chlorinatable than polychloroprene are included in said dispersion or solution. Preferably, the article is a polychloroprene glove containing carboxylated nitrile rubber, carboxylated styrene butadiene or polyisoprene.
Claims1
A double-donnable chlorinated polychloroprene article comprising polychloroprene and a polymer, wherein the polymer is selected from the group consisting of:
- carboxylated nitrile rubber comprising carboxylic acid, acrylonitrile and butadiene;
- carboxylated styrene butadiene;
- and polyisoprene;
- wherein the polychloroprene article comprises, before chlorination of the article, between 3.4% to 17.2% by weight of the polymer and;
- wherein the carboxylated nitrile rubber comprises, before chlorination of the article, (by weight) 3-6% carboxylic acid, 20-40% acrylonitrile, and 60-80% butadiene, and wherein the article is a glove comprising, on the internal, user-contacting surface thereof, a layer of hydrogel.
