Abstract

An emulsion polymerized synthetic rubber latex is treated to reduce its viscosity and/or increase the size of dispersed polymer particles by flowing the latex through a constriction at a pressure not less than 1,000 p.s.i.g., the latex having a concentration of dispersed polymer particles of not less than 15%. The initial average size of the polymer particles may be greater or less than 1,000A DEG , the concentration of the dispersed particles may be in the range 35 to 50%, the pressure in the range 1,000 to 10,000 p.s.i.g., the pH of the latex to be treated in the range 7 to 13 (preferably 7-11), the temperature at the constriction 0-80 DEG (preferably 0-50 DEG C.) and the constriction may be in the form of an orifice of a homogenisin valve. The latex may be of a copolymer of a conjugated diolefin with an aryl olefin or acrylonitrile, a homopolymer of a conjugated diolefin or a polychloroprene.
