Description

Processes for the polymerization of olefins in which late transition metal complexes, such as nickel, iron, co-balt and palladium complexes, are used as a polymerization catalyst have improved polymer productivity when oxidizing agents (like among others iodine, trichlorotoluene) are present during at least a portion of the polymerization. The polymers produced are useful as elastomers, for packaging films, and molding resins.

Procédés de polymérisation d'oléfines dans lesquels des complexes de métaux de transition tardive tels que des complexes de nickel, de fer, de cobalt et de palladium sont utilisés comme un catalyseur de polymérisation possédant une meilleure productivité de polymères lorsque les agents de polymérisation sont présents pendant au moins une partie du processus de polymérisation. Les polymères ainsi produits sont utiles en tant qu'élastomères, dans des films d'emballage et des résines à mouler.
