Catalyst comprising a cation Activator which is a Bronsted acid capable of donating a Proton and anion not compatible Inert CoordinatorCatalyst system and polymerization process that comprises by Said System.

摘要

These are catalyst activators comprising a cation that is a Bronsted acid capable of donating a proton, and an inert, compatible, non-coordination anion, characterized by a constant solubility at 25 ° C in hexane, cyclohexane or methylcyclohexane of al minus 5 percent by weight. Catalytic systems comprising said Group 4 activators and metal complexes and the polymerization processes where said catalytic systems are applied are also proposed.
