METHOD FOR PRODUCTION OF POLYOLEFINS Russian patent published in 1997 - IPC

Abstract RU 2078771 C1

FIELD: organic chemistry. SUBSTANCE: method involves (co)polymerization of olefins having common formula R^a=CH=CH-R^b or R^a-CH=CH-R^b where R^a and R^b are the same or different and are chosen of hydrogen and C₁-C₁₄-hydrocarbon residue. Said process is carried out at (-60)-200 C and at 0.5-100 var. Metallocene (e. g. rac-dimethyl-silyl-bis(1-(2-methyl-4-ethylenedenyl)-zirconium dichloride or rac-dimethyl-bis(1-(2-methyl-4-isopropylyndenyl)-zirconium dichloride is used as said catalyst, cyclic or linear aluminoxane being used as cocotalyst. EFFECT: improved efficiency of the method. 7 cl, 2 tbl
