Abstract

Olefins are polymerized in the presence of a catalyst comprising (1) an organometallic compound of a transition metal of general formula RnMeXv-n wherein R is an indenyl or fluorenyl radical, unsubstituted or alkyl substituted or aryl substituted; Me is a transition metal of Group IV or V of the Mendel<\>aeeff Periodic Table; X is a halogen, an alkoxy, aryloxy or cycloalkoxy group containing 1 to 12 carbon atoms or a radical of an organic acid; n is 1 or 2 and v is the maxium valency of the transition metal; and (2) an alkyl, aryl, haloalkyl or haloaryl derivative of a metal of Group Ia, IIa, IIb or IIIa of the Mendel<\>aeeff Periodic Table. The olefin may be ethylene or propylene. The transition metal compound may be an ethoxy, butoxy, isobutoxy, cyclohexyloxy or nonoxy indenyl or fluorenyl titanium, zirconium or vanadium. The Group I to III metal compound may be butyl lithium, amyl sodium, diethyl magnesium, ethyl magnesium chloride, ethyl magnesium bromide, n-butyl magnesium chloride, phenyl magnesium bromide, triethyl aluminium, triisobutyl aluminium, diethyl aluminium chloride, diethyl aluminium hydride, or lithium aluminium tetraethyl. In place of the transition metal compound per se the reaction product of titanium tetrabromide, vanadium pentachloride or zirconium tetraiodide with an indenyl or fluorenyl alkali metal or Grignard compound may be used. Polymerization may be effected in an inert solvent, e.g. benzene, heptane or cyclohexane. Examples describe the polymerization of ethylene in the presence of catalysts comprising (1) diindenyl titanium dibromide and triethyl aluminium, (2) the reaction product of tetranonoxy titanium and p indenyl sodium and ethyl magnesium bromide, (3) the reaction product of tetrabutoxy titanium and indenyl lithium and ethyl magnesium bromide, (5) diindenyl titanium diiodide and triethyl aluminium, (6) the reaction product of zirconium tetrachloride and indenyl lithium and triethyl aluminium, and (7) the reaction product of tetrabutoxy titanium and indenyl lithium and triethyl aluminium; and the polymerization of propylene in the presence of a catalyst comprising (4) difluorenyl titanium dibromide and triethyl aluminium.
