FIELD: chemistry.
SUBSTANCE: invention relates to dispersions of high-molecular compounds. Disclosed is a method of producing stable synthetic polymer dispersions of siloxane rubber, comprising preparing a solution of siloxane rubber in chloroform, adding an aqueous solution of a cationic surfactant (Catamin AB) to the obtained solution, further, while stirring on a magnetic mixer at rate of 300 rpm to obtain an emulsion which is dispersed in a rotor-stator homogenizer for 10 minutes at a rotor speed of 20,000 rpm, followed by removal of chloroform on a rotary evaporator and evaporation of water to obtain a concentrated polymer dispersion.
EFFECT: disclosed method increases stability of final dispersions of siloxane rubber.
