METHOD OF EXTRACTING SYNTHETIC RUBBER Russian patent published in 2012 - IPC C08C2/06

Abstract RU 2448121 C1

FIELD: chemistry.

SUBSTANCE: method of extracting synthetic rubber from hydrocarbon solutions is realised through aqueous degassing in the presence of an adhesion reducing powder which is in form of a mixture of potassium and calcium salts of a product of reaction of alkyl succinic anhydride and a copolymer of α-olefin and maleic anhydride in weight ratio from 1:99 to 10:90, respectively.

EFFECT: invention enables to obtain rubber, having improved ash content and colour characteristics, with low consumption of adhesion reducing powder.
