Abstract

Linear alpha-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 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 2); in the presence of a diluent, at a temperature below 75% C., at an ethylene pressure above 50 p.s.i.a., the mole ratio of ethylene to the olefin reaction product being above 0.8, and a base being added to the reaction mixture in order to terminate the reaction. Suitable diluents include benzene, chlorotoluene, tetrahydronaphthalene and dichloromethane, others being mentioned. The catalyst may be modified by the presence of a C1- 15 alcohol. The base used to terminate the reaction may be an alkali metal or alkaline earth metal hydroxide or carbonate, ammonium hydroxide, a quaternary ammonium base, or a Lewis base, such as ammonia, an amine, a cyclic nitrogen base, or an ether. Water, an alcohol, or a glycol may also be added to kill the catalyst, either before, after, or simultaneously with, the base.ALSO:Linear alpha-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 2); in the presence of a diluent, at a temperature below 75 DEG C., at an ethylene pressure above 50 p.s.i.a., the mole ratio of ethylene to the olefin reaction product being above 0.8, and a base being added to the reaction mixture in order to terminate the reaction.
