METHOD OF PIPERYLENE OLIGOMERS Russian patent published in 1999 - IPC

Abstract RU 2141973 C1

FIELD: film-forming agents and rubbers product modifiers. SUBSTANCE: method comprises polymerizing piperylene-containing mixture in the presence of catalyst in toluene, using molecular weight regulator and desactivator in mixing reactors, stages of polymerization, catalyst formation, chain termination and desactivation being carried out under conditions of developed turbulent motion in tubular sectional reactor or tubular sectional reactors located in series or in tubular sectional reactors operating in parallel. Method makes it possible to provide identical polymerization conditions throughout entire process, increase efficiency and obtain homogeneous and light polymer. EFFECT: more efficient preparation process. 3 dwg
