FIELD: chemistry.
SUBSTANCE: invention relates to anti-agglomerators which eliminate stickiness of rubber crumbs after the water degassing step when producing synthetic rubber by solution polymerisation during separation thereof from hydrocarbon solvents. The anti-agglomerator is a 20-40% solution in base mineral and synthetic oils without additives of a mixture of calcium salts of alkylbenzene sulphonic acids with the length of the hydrocarbon chain of alkyl substitutes ranging from C12 to C26 and overall base number ranging from 20 to 390 mg KOH/g.
EFFECT: high alkalinity of the aqueous medium at the degassing step, longer time between repairs of rubber drying equipment, low material consumption.
