ABSTRACT:
Butyl rubber or EPDM elastomer latices having excellent mechanical stability are prepared by emulsifying the elastomer cement (hydrocarbon solution) with water, a water-soluble soap of a fatty acid containing 12 to 24 carbon atoms using an alkali metal or ammonium radical to form the soap and a second stabilizer additive which is an alkali metal, ammonium or amine salt of a long chain alpha olefin polymeric or copolymeric substituted organic aliphatic mono or dicarboxylic acid or anhydride thereof of a number average molecular weight between about 500 and about 3500 and thereafter removing the hydrocarbon solvent therefrom by flashing the same off by steam or vacuum distillation or other suitable solvent separation method.
