α-olefins and olefin polymers and processes therefor

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