Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
173 words
A process for preparing a solid particulate catalyst component comprising (A) reacting reactants comprising (1) a vanadium compound having a V--X linkage where X is halogen, (2) an organoaluminum compound selected from those having the formula AlR' n X 3-n wherein X is halogen, each R' is individually selected from the group consisting of alkyl radicals, aryl radicals, cycloalkyl radicals, and alkoxy radicals, and n is a number from 1 to 3, and (3) an organophosphorus compound having a P--L linkage wherein L is selected from the group consisting of alkyl radicals, alkoxy radicals, aryl radicals, aryloxy radicals, cycloalkyl radicals, cycloalkyloxy radicals, cycloalkylaryl radicals, alkylamino radicals, and haloalkyloxy radicals, or (B) reacting reactants comprising said organoaluminum compounds as defined for (2) and a composition having functionality of the formula ##STR2## wherein each L is individually selected from the group consisting of the L's as defined for (3), under suitable conditions in a liquid which allows the product of the reaction to form as a particulate solid, said liquid consisting essentially of nonaromatic halocarbon.
Claim 2
Dependent Claim
