FIELD: petrochemical industry.
SUBSTANCE: invention refers to manufacture of synthetic rubbers that are obtained by means of emulsion copolymerization, notable to the stage of their extraction from latex, and can be applied in petrochemical industry. In the salt-free congelation method rubbers that contain leukanol-oil dispersing agent are employed. The rubbers are obtained by emulsion copolymerization of butadiene with the monomers of the vinylic row. As a coagulating agent, quaternary ammonium compounds are used that are based on resin acids and colophony Biozic by means of introduction of 3-5 kg of an active substance into the latex per 1 t of the rubber.
EFFECT: production of the rubber at one stage in the form of big, unadhesive, homogeneous, finely set chips in the acid environment, improvement of the quality of the obtained rubber.
