Abstract: Certain nickel [II] complexes of selected ortho-phosphine substituted arylsulfonamides or selected phosphine containing alkylsulfonamides catalyze the polymerization of ethylene. The polymers produced may be used as lubricants or in waxes. Some of these nickel [II] complexes and the phosphine containing ligands are also novel compounds.

Abstract: Propylene may be polymerized by contacting it with certain iron complexes of selected 2,6-pyridinecarboxaldehydebis(imines) and 2,6-diacylpyridinebis(imines). The polymers produced are useful as molding resins.

Abstract: Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear .alpha.-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected .alpha.-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected .alpha.

Abstract: Alpha-olefins are manufactured in high yield and with very high selectivity by contacting ethylene with an iron complex of a selected 2,6-pyridinedicarboxaldehyde bisimine or a selected 2,6-diacylpyridine bisimine, and in some cases a selected activator compound such as an alkyl aluminum compound. Novel bisimines and their iron complexes are also disclosed. The .alpha.-olefins are useful as monomers and chemical intermediates.

Abstract: Disclosed is a process for the production of chemical intermediates by the cross dimerization of two compounds containing carbon-carbon double bonds, wherein said process is catalyzed by a nickel II catalyst which is a complex with .eta..sup.3 carbon-based allyl or substituted allyl, trisubstituted phosphine, and a weakly coordinating ligand. This catalyst may be used to selectively cross-dimerizes ethylene and methyl acrylate to give methyl 4-pentenoate, a nylon 6,6 intermediate.
