Hydrocarbon soluble catalyst supports and resultant polymerization catalysts
A method is described for carrying out polymerization reactions utilizing at least one olefin containing from 2 to 30 carbon atoms in a solution polymerization system contacting the olefin with a catalyst prepared by a method comprising (a) contacting a hydrocarbon insoluble magnesium compound; (b) non-halide transition metal alkoxides having at least one general formula MO/sub g/(OR/sup 4/)/sub r/, RO(M(OR)/sub 2/O)/sub p/R/sup 4/, R/sub x/M(OR/sup 4/)/sub y/ wherein M is titanium, vanadium, chromium or zirconium, each R/sup 4/ is, independently, alkyl groups containing from 1 to 20 carbon atoms, aryl groups, alkaryl groups, and aralkyl groups each containing from 6 to 20 carbon atoms as defined, g is 0 or 1, r is 2 to 4, and 2g+r is equal to the valence of M; p is at least 2; and x+y is equal to the valence of M and the magnesium to titanium ratio is at least 1:1, then (c) reacting the mixture of (a) and (b) with a halogenating agent to obtain a polymerization catalyst having halogen to magnesium ratio of at least 2.0.
