METHOD FOR PRODUCTION OF (CO)POLYMERS OF CONJUGATED DIENES Russian patent published in 1997 - IPC

Abstract RU 2076113 C1

FIELD: technology of production of (co)polymers of conjugated dienes. SUBSTANCE: polymerization of butadiene-1,3 or copolymerization of butadiene-1,3 with styrene is carried out in the presence of catalyst. 2-ethylhexyl of sodium (its quantity being 5-50 moles per 1 kg of monomers) together with compound having common formula CH2=C=C=CH-R where R is alkyl-C1-C3 (its quantity being 0.5-10.0 moles per 1 mole 2-ethylhexyl of sodium) is used as said catalyst. EFFECT: improves efficiency of the method. 2 tbl
