Abstract

Catalyst for the polymsn. of an alpha-alkane in a liquid diluent is prepd. by (a) reacting an Al cpd. of formula RmAlX3-m (where R is hydrocarbyl; x is halogen; and m 3) with an org. Mg cpd., (b) combining the reaction mixt. with a tetravalent Ti cpd. and/or another transition metal cpd. esp. a V cpd., (c) opt. washing and/or heating the formed catalyst suspension, and (c) activating the catalyst suspension with an organo-Al cpd. When m in RmAlX3-m is =2 and the ratio X:Mg is >=1, the transition metal cpd. consists exclusively of a tetravalent Ti cpd. The molar ratio Al + Mg to transition metal cpd. is 100 (0.1-10) esp. 0.5-5. The molar ratio of halogen in the Al cpd. to Mg is 0.01-100, esp. 0.2-10. X is A and R is 1-4C alkyl. The Mg cpd. is dibutylmagnesium. Catalyst gives very high polymer yields, and catalyst residues do not have to be removed from the polymer.
