METHOD OF OBTAINING LOW-MOLECULAR CARBO-CHAIN POLYMERS Russian patent published in 2009 - IPC C08F36/04 C08F2/42

Abstract SU 1840785 A1

FIELD: chemistry.

SUBSTANCE: invention relates to field of obtaining lowmolecular rubbers and can be applied in oil-chemical industry. Low molecular polymers are obtained by polymerisation of conjugated dienes, their co-polymerisation with each other or with vinyl monomers in hydrocarbon medium at 70-1300°C in presence of hydro-peroxide initiators, molecular mass regulators and terpolymerisation inhibitors, inhibitor and initiator being first diluted with solvent selected from group, containing alcohols, ketones, and aliphatic, cycloaliphatic or aromatic C₅-C₈ hydrocarbons, to concentration by inhibitor 0.1-1.0 wt % and by initiator 9-40 wt %.

EFFECT: reduction of polymer depositions on equipment, ensuring process continuity and improvement of accident prevention conditions.
