FIELD: chemistry.
SUBSTANCE: invention relates to technology of separating diene rubbers from polymerisate and can be applied in oil-chemical industry. Method is realised by processing of polymerisate with water steam, condensation of obtained steam- hydrocarbon mixture and separating of hydrocarbons from condensate, separation of hydrocarbons being carried out by extraction with water-insoluble hydrocarbon solvents with boiling temperature -4-70°C with volume ratio of extragent condensate from 0.3:1 for 2:1.
EFFECT: ensuring more complete extraction of hydrocarbons, reduction of electricity consumption and increase of waste water purity.
