Abstract

Cyclic polyolefines are obtained by polymerizing a conjugated acyclic diene at 40-250 DEG C. in the presence of a compound of the formula [Rx(RO)3-xZ]3NiCO, or mixtures of such compounds where each R is the same or different organic radical, x is 0, 1, 2 or 3 and Z is P, As or Sb. The diene may be butadiene or a derivative thereof, e.g. isoprene, piperylene, phenyldiolefines, chloroprene, 2,3-dichlorobutadiene and 2,3-dimethylbutadiene, the products being 4-vinylcyclohexene, octadiene-1,5 and cyclodecatriene-1,5,9, or the corresponding derivatives. In the catalyst, the group R may be methyl, ethyl, propyl, butyl, hexyl, dodecyl, isooctyl, isobutyl, isopentyl, cyclopentyl, cyclohexyl, cyclooctyl, phenyl, biphenyl, a - or b -naphthyl, p-chlorophenyl, 2-chloroethyl, m-(trifluoromethyl) phenyl, bromocyclohexyl, m-, o-, or p-tolyl, 3,5-xylyl, p-methoxyphenyl, p-acetophenyl or a heterocyclic compound. The catalyst may be mixed with the corresponding compound [Rx(RO)3Z]2Ni(CO)2 and is used in amounts of 0.001-10% by weight of the diene. The reaction may be effected in a hydrocarbon solvent for 0.05-2 hours.
