Catalyst compositions useful for the polymerization or oligomerization of olefins are disclosed. Certain of the catalyst compositions comprise N-pyrrolyl substituted nitrogen donors. Also disclosed are processes for the polymerization or oligomerization of olefins using the catalyst compositions.

Catalysts containing N-pyrrolyl substituted nitrogen donors

Catalyst compositions useful for the polymerization of olefins are disclosed. These compositions comprise a Group 8-10 metal complex comprising a bidentate or variable denticity ligand comprising one or two nitrogen donor atom or atoms independently substituted by an aromatic or heteroaromatic ring(s), wherein the ortho positions of said ring(s) are substituted by aryl or heteroaryl groups. Also disclosed are processes for the polymerization of olefins using the catalyst compositions.

Catalysts containing per-ortho aryl substituted aryl or heteroaryl substituted nitrogen donors

Improved Group 8-10 transition metal based supported catalyst processes for the polymerization of olefins are described. Some of the improvements pertain to protocols for catalyst preparation and activation which improve the catalyst productivity in the presence of hydrogen as a molecular weight control agent.

Olefin polymerization processes using supported catalysts

Catalyst compositions useful for the polymerization or oligomerization of olefins are disclosed. Certain of the catalyst compositions comprise metal complexes of mono through tetradentate ligands comprising N-pyrrolyl substituted nitrogen donors bonded to the metal. Also disclosed are processes for the polymerization or oligomerization of olefins using the catalyst compositions.

A process is provided for the production of an emulsifiable polypropylene wax having a melt viscosity from 1000 to 5000 cP at 190.degree. C. This process entails reacting at a temperature below 190.degree. C. a thermally degraded polypropylene wax having a melt viscosity below 1000 cP (at 190.degree. C.) with maleic anhydride in the presence of a free radical source. Floor polish formulations containing this polypropylene wax are very clear but yet provide floor finishes that are very tough.

Process for painting polypropylene

This invention relates to improved catalysts for the polymerization of propylene and higher .alpha.-olefin in a high temperature solution process comprising (1) a beta amino carboxylic ester, (2) an aluminum trialkyl and (3) a transition metal halide. More particularly, this invention relates to catalysts for the catalytic high temperature solution polymerization of .alpha.-mono-olefins containing at least 3 carbon atoms to form solid, highly crystalline polymers. More specifically, the catalysts of the present invention produce polypropylene in a high temperature solution process at very high polymer to catalysts yields.
