Изобретение относится к производству маслонаполненных бутадиен-( a -метил)-стирольных каучуков, получаемых эмульсионной сополимеризацией, в частности к способам выделения их из латексов, и может быть использовано в нефтехимической промышленности. Задачей, на решение которой направлено данное изобретение, является стабилизация, процесса коагуляции, упрощение технологии и улучшение свойств маслонаполненного бутадиен-( a -метил)-стирольных каучуков. Это достигается тем, что в известном способе выделения маслонаполненных бутадиен-( a -метил)-стирольных каучуков, заключающемся в коагуляции латекса водным раствором хлорида натрия и минеральной кислотой, включающем рецикл серума, концентрирование крошки каучука, промывку ее водой с последующим отжимом и сушкой, в качестве коагулянта использован продукт взаимодействия белка с четверичной полимерной солью поли-N, N-диметил-N,N-диаллиламмоний хлоридом в сочетании с хлоридом натрия при следующем массовом соотношении компонентов (на сухое вещество),%мас.: хлорид натрия 83 - 97, белок 12 - 2,8, поли-N, N-диметил- N, N-диаллиламмоний хлорид 0,2 - 5,0.The invention relates to the production of oil-filled butadiene (a-methyl) -styrene rubbers obtained by emulsion copolymerization, in particular to methods for isolating them from latexes, and can be used in the petrochemical industry. The problem to which this invention is directed is the stabilization of the coagulation process, the simplification of technology and the improvement of the properties of oil-filled butadiene (a-methyl) -styrene rubbers. This is achieved by the fact that in the known method of isolating oil-filled butadiene (a-methyl) -styrene rubbers, which consists in coagulating the latex with an aqueous solution of sodium chloride and mineral acid, including recycling the serum, concentrating the rubber crumb, washing it with water, followed by pressing and drying As a coagulant, the product of the interaction of the protein with the quaternary polymeric salt of poly-N, N-dimethyl-N, N-diallylammonium chloride in combination with sodium chloride was used with the following mass ratio of components (for dry ETS),% wt .: Sodium chloride 83 - 97 Protein 12 - 2,8, poly-N, N-dimethyl-N, N-diallilammony chloride 0.2 - 5.0.
