1289927 Artificial latex SNAM PROGETTI SpA 19 April 1971 [16 April 1970] 27001/71 Heading C3P Following the emulsification in water of a solution of a polymer in an organic solvent, the solvent is partially or totally removed by contacting the emulsion with a solid adsorbent material which is insoluble in both water and the solvent, is compatible with the solvent, and is substantially incompatible with the polymer. Examples describe the removal of n-hexane from an emulsion containing cis-polyisoprene by repeated treatment with either cured cis-1,4- polybutadiene or cured ethylene/propylene/ 1,4-hexadiene terpolymer as adsorbents.
