In the articlethe estimation of coagulating ability using cationic electrolytes is shown.It was found that in the case of using low molecular weight cationic electrolyte, the completeness of the release of rubber from latex is achieved at their consumption of 20–30 kg/t of rubber. A feature of the behavior of cationic surfactants in the latex coagulation has been established. It is shown that the consumption of cationic surfactants corresponds to the consumption of polymer cationic electrolytes. Also, a hypothesis was put forwardthatcationic surfactants violate the aggregate stability of latex systems and the mechanism of action, which is basedon the interaction of cationic surfactant micelles with latex globules carrying anionic surfactants on the surfaceis proposed.The use of cationic surfactants can eliminate the use of sodium chloride in the industry of separating emulsion styrene-butadiene rubber from latex, as well as solve some environmental problems.The final stage of theinvestigationwas to determinethe parametersof rubber compounds and vulcanizates based on the rubber. These rubbers, rubber compounds and vulcanizates correspond to standard parameters.
