Abstract
1346621 Forming polymer latices ESSO RESEARCH & ENG CO 25 Nov 1971 54789/71 Headings C3G and C3P Latices are prepared by adding water and an emulsifier to a dispersion of a polymer selected from natural rubber and polymers of C 2-20 ethylenically unsaturated monomers in an organic solvent which itself or as an azeotrope with water has a boiling point lower than that of water at atmospheric pressure, to form an aqueous emulsion having particles of precursor latex size (about 20 microns), dispersing the emulsion in a moving flow of steam as initial continuous phase while subjecting the phases to a decrease of pressure and maintaining the temperature thereof below the limiting temperature for stability of the emulsion, thereby vaporizing solvent from the dispersed droplets, impinging the flow of droplets and vapour obtained on another flow of latex of the polymer and separating the liquid and gaseous phases resulting. A separating zone may be established at a pressure below that at which admixing with the steam is effected and through which the other latex is passed. Apparatus suitable for carrying out the process of the invention is described and illustrated, and many suitable polymers, solvents and emulsifiers are specified. Examples describe the formation of latices of (1 and 3) butyl rubber, (2) ethylene/propylene rubber, (4) amorphous polypropylene, (5) polyisobutylene reinforced with silica, (6) polyisobutylene reinforced with silica or carbon black, (7) butadiene/styrene copolymer grafted with 2-vinylpyridine in the presence of cumene hydroperoxide and tetraethylene pentamine, (8) cis-1,4-polybutadiene reinforced with silica, (9) polyisobutylene, (10) polyisobutylene and petroleum resin, (11) ethylene/propylene rubber and petroleum resin and (12) butyl rubber and coumarone/indene resin.
