Abstract
A composition of matter is provided comprising a catalytic mixture resulting from contacting at least one of each of the following compounds, an pyridine compound, a clay compound, and an organo-nickel compound. Additionally, a process is provided comprising contacting, under polymerization conditions, at least one alpha-olefin, with a catalytic mixture resulting from contacting at least one of each of the following compounds, an pyridine compound, a clay compound, and an organo-nickel compound.
Claims14
A composition of matter comprising a catalytic mixture resulting from contacting:
- at least one pyridine compound having the formula ##STR2## wherein each R is independently selected from the group consisting of hydrogen and --COOH, provided that at least one R group is a --COOH group;
- at least one organo-nickel compound wherein the nickel is in the zero valence state before formation of the active nickel component;
- and
- at least one clay compound wherein the weight ratio of said clay compound to said nickel is from about 1 to about 400.
A composition of matter comprising a catalytic mixture resulting from contacting:
- (a) pyridine-2-carboxylic acid;
- (b) bis(1,5-cyclooctadiene) nickel;
- and
- (c) a clay compound selected from the group consisting of sepiolite, bentonite, and mixtures thereof;
- wherein the weight ratio of clay compound to nickel is from about 1 to about 500.
