METHOD OF PRODUCING SYNTHETIC LATEX Russian patent published in 2014 - IPC C08J3/07 C08J3/02 C08F6/14

Abstract RU 2507218 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing synthetic latex from rubber. The method comprises steps of: (a) emulsifying a binding substance containing rubber, which is dissolved in a suitable organic solvent, together with an aqueous surfactant solution to form an oil-in-water emulsion; (b) step-by-step reduction of content of solvent in the oil-in-water emulsion in two or more steps, resulting in formation of synthetic latex. Also described is a reactor with continuous mixing for removing the organic solvent from the oil-in-water emulsion, which contains rubber dissolved in the organic solvent.

EFFECT: reducing the amount of residual solvent to very low levels with high efficiency of the process.
