Supported catalysts with donor-acceptor interaction

摘要

A catalyst system based on a transition metal compound with one or more donor-acceptor reversible bonds (and optionally also co-catalyst) comprises a support which is an ion-exchanging material with a layered lattice structure. Independent claims are included for: (1) use of the catalyst to polymerize the following monomers: alpha -olefins, i-olefins, cycloolefins, alkenes and/or diolefins; and (2) the use of the polymers thus obtained in the production of molded or shaped articles of all types.
