METHOD OF OBTAINING POLYMERS, WHICH DO NOT CONTAIN WATER AND SOLVENTS Russian patent published in 2015 - IPC C08F6/10 B01D19/00 B29B7/84 C08C2/00 C08L9/00 C08L23/22 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of removing volatile compounds from a flowing medium, containing, at least, one non-volatile polymer, which represents synthetic rubber and, at least, one volatile compound, as well as to a device, suitable for the realisation of the said method. The method includes the following stages: a) processing the flowing medium in, at least, one unit of a concentrator, in which the flowing medium is heated, after which the concentrated flowing medium is supplied into a degassing tank and re-heating at stage b) in a reheating unit. After that, the reheated flowing medium is supplied to stage c) into, at least, one extruder unit. The extruder unit contains, at least, a degassing section of the extruder, from which volatile compounds are removed via ventilation ports and steam lines, as well as, at least, a transportation section, an accumulation section and a discharge section.

EFFECT: continuous energy-efficient, environmentally and economically preferable method of removing volatile compounds with obtaining a polymer product based on synthetic rubber, which virtually does not contain volatile compounds.
