METHOD OF BUTADIENE-STYRENE RUBBER PRODUCING Russian patent published in 1998 - IPC

Abstract RU 2101301 C1

FIELD: rubber industry. SUBSTANCE: method involves copolymerization of butadiene and styrene in medium of hydrocarbon solvent in the presence of organometallic catalyst. Method involves purification of monomers and solvent by rectification from high-boiling hydrocarbons, azeotropic drying and adsorption purification. Purification of solvent and butadiene by rectification from high-boiling hydrocarbons and azeotropic drying is carried out in common and purification of styrene by adsorption - separately followed by combining the obtained flows and their feeding to adsorption purification and then - to polymerization. EFFECT: improved method of rubber producing. 2 tbl, 1 dwg
