METHOD OF PREPARING CATALYST FOR CIS-COPOLYMERIZATION OF CONJUGATED DIENES Russian patent published in 1995 - IPC

Abstract RU 2049092 C1

FIELD: petroleum chemical industry. SUBSTANCE: method involves interaction of lanthanide halides or their alcohol complexes with organoaluminium compound in the medium of hydrocarbon solvent in the presence of piperylene under condition of mechanical crushing in vibrational mill for 3-30 hr, at the room temperature. Mole ratio of organoaluminium compound lanthanide compound is from 0.2:1 to 5:1 and that of piperylene lanthanide compound is from 1:1 to 5:1. EFFECT: improved method of catalyst preparing. 3 tbl
