Abstract

Linear olefins having number average M.W.'s of 70-300 are prepared by polymerizing ethylene in the presence of a catalyst comprising the reaction product of a compound of formula TiX4, TiX3OR1, or TiX3OOC.R1 (where is Cl or Br, and R1 is alkyl, allyl, aralkyl or cycloalkyl), and an aluminium alkyl compound such that the ultimate formula of the aluminium alkyl compound is AlRnX3- n (where X is Cl, Br or I, R is alkyl aralkyl or cycloalkyl, and n is less than 1); in the presence of an aromatic hydrocarbon or halogenated aromatic hydrocarbon diluent, at a temperature below 75 DEG C., at an ethylene pressure above 50 psia, and the mole ratio of ethylene to the olefin product being above 0.8. The diluent may be a mixture also containing an aliphatic or naphthenic solvent, provided the aromatic solvent constitutes at least 40% of the mixture. The products comprise at least 90 mole per cent linear olefins. The catalyst may be modified by the presence of a C1- 8 alcohol, and the reaction may be terminated by adding a base or Lewis base.ALSO:Linear olefins having number average M.Ws of 70-300 are prepared by polymerizing ethylene in the presence of a catalyst comprising the reaction product of a compound of formula TiX4, TiX3OR1, or TiX3OOC.R1 (where X is Cl or Br, and R1 is alkyl, allyl, aralkyl or cycloalkyl), and an aluminium alkyl compound such that the ultimate formula of the aluminium alkyl compound is AlRnX3- n (where X is Cl, Br or I, R is alkyl, aralkyl or cycloalkyl, and n is less than 1); in the presence of an aromatic hydrocarbon or halogenated aromatic hydrocarbon diluent, at a temperature below 75 DEG C., at an ethylene pressure above 50 p.s.i.a., and the mole ratio of ethylene to the olefin product being above 0.8.
