PROCESS FOR PREPARING SYNTHETIC RUBBERS Russian patent published in 1999 - IPC

Abstract RU 2125576 C1

FIELD: technology of preparation of synthetic rubbers. SUBSTANCE: claimed process for preparing synthetic rubbers by degassing from solutions in hydrocarbon solvent comprises preconcentrating rubber dispersion in water in two stage, first directly at outlet from the last degassing stage with hot water recycling to crumb-forming degassing stage, and then before partially concentrated rubber dispersion is admitted into settling concentrator with water delivered to prepare suspension or solution of rubber crumb and/or for purification. EFFECT: greater amount of circulating water removed from rubber dispersion and reduced discharges of hydrocarbons into atmosphere. 1 dwg, 2 ex
