Abstract
Disclosed heroin arc processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic eaters a carboxylic acids, and other monomers. The polymerizations are catalysed 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 a.olefins by the oligomerization of ethylene using as a catalyst system a combination of a nickel compound having a selected .alpha.-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected $(a)diimine nickel complexes with ethylene.
