The present invention relates to a catalyst mixture containing at least one metal complex according to the formula (1)CyLMZ&#x2003;&#x2003;(1),

Catalyst mixture

The invention relates to a process for the preparation of a polymer comprising monomeric units of ethylene, an &#x3b1;-olefin and a vinyl norbornene applying as a catalyst system: a. a bridged or an group 4 metal containing an unbridged catalyst having a single cyclopentadienyl ligand and a mono substituted nitrogen ligand, wherein said catalyst is defined by the formula (I): b. an aluminoxane activating compound, c. 0-0.20 mol per mol of the catalyst of a further activating compound, wherein Y is a substituted carbon or nitrogen atom. The invention further relates to a polymer obtainable with the process of the invention. 

Process for the production of a polymer comprising monomeric units of ethylene, an A-olefin and a vinyl norbornene

The invention relates to a process for the preparation of a polymer comprising at least one aliphatic or aromatic hydrocarbyl Colefin in the presence of an ionic catalyst, comprising an organometallic compound and an activator, and optionally a scavenger.

Polymerization catalyst comprising amidine ligand

The invention relates to a process for the preparation of a polymer comprising monomeric units of ethylene, an &#x3b1;-olefin and a vinyl norbornene applying as a catalyst system: a. a bridged or an group 4 metal containing an unbridged catalyst having a single cyclopentadienyl ligand and a mono substituted nitrogen ligand, wherein said catalyst is defined by the formula (I): b. an aluminoxane activating compound, c. 0-0.20 mol per mol of the catalyst of a further activating compound, wherein Y is a substituted carbon or nitrogen atom. The invention further relates to a polymer obtainable with the process of the invention.
