METHOD OF PREPARING HYDROXYL-CONTAINING TELECHELATE OLIGODIENES Russian patent published in 2003 - IPC

Abstract RU 2209212 C2

FIELD: polymerization processes. SUBSTANCE: title oligodienes are obtained via radical polymerization of dienes initiated by bifunctional azonitriles, in particular polymerization of diolefins or copolymerization of diolefins with acrylonitrile initiated by 4,4'-azo-bis(4-cyanovaleric acid) in presence of alpha-epoxy compound selected from ethylene oxide, propylene oxide, and epichlorohydrin at 60-80 C. EFFECT: optimized polymerization conditions. 2 tbl, 7 ex
