Olefin dimerisation using nickel and aluminium catalyst - prepd. from vinyl pyridine grafted rubber, nickel salt and (organo)aluminium cpd
olefins are dimerised by mixing with a catalyst (I) in an opt. halogenated hydrocarbon solvent (II) at 0-100 degrees C and 1-40 atm. (I) is a grafted copolymer of natural or synthetic rubber and vinyl pyridine, which swells in (II) and contains 0.5-40 wt. % polyvinylpyridine sequences with which is...
