Composition and method for manufacturing coagulable chlorosulfonated polyethylene latex and articles are disclosed. Chlorosulfonated polyethylene solid rubber is converted to chlorosulfonated polyethylene latex that can produce strong elastic dry film. Sodium alkylbenzene sulfonate is used as an emulsifier to provide stable emulsion of ionic chlorosulfonated polyethylene latex. Anioinc ammonium salt of alginic acid solution is used as a creaming agent to provide effective creaming function and produce high yield, stable, coagulable ionic chlorosulfonated polyethylene latex. Epoxy resin, sulfur, zinc oxide, rubber accelerators and polymeric hindered phenol antioxidant are used to prepare chlorosulfonated polyethylene latex compositions for making high strength chlorosulfonated polyethylene articles.
An elastomeric latex article comprising the product of a coagulable, film forming elastomeric chlorosulfonated polyethylene and an epoxy resin, wherein the epoxy resin comprises oxirane, 2,2′-((1-methylethylidene)bis(4,1-phenyleneoxymethylene))bis-,homopolymer epoxy resin in a preferred amount ranging from about 5.0 to 35.0 parts per hundred parts of chlorosulfonated polyethylene.
