Selected olefins such as ethylene and .alpha.-olefins are polymerized by nickel [II] complexes of certain monoanionic ligands. The polyolefins are useful in many applications such as molding resins, film, fibers and others. Also described are many novel nickel compounds and their precursors, as well as novel ligands.
L'invention concerne des oléfines sélectionnées, telles que l'éthylène et les .alpha.-oléfines, polymérisées par des complexes au nickel [II] de certains ligands mono-anioniques. Ces polyoléfines sont utiles dans de nombreux domaines d'application, notamment dans les résines à mouler, les films et les fibres. L'invention concerne également de nombreux composés de nickel nouveaux et leurs précurseurs, ainsi que de nouveaux ligands.
