Process for making a copolymer by copolymerising (1) ethylene with (2) at least one comonomer selected from aliphatic C-Calpha-olefins and (3) 5-ethylidene-2-norbornene, including contacting the monomer with a catalyst comprising a transition metal compound having the following Formula A, and an activating quantity of a suitable activator of the formula shown herein, wherein Z comprises a five-membered heterocyclic group, the five membered heterocyclic group containing at least one carbon atom, at least one nitrogen atom and at least one other hetero atom selected from nitrogen, sulphur and oxygen, the remaining atoms in the ring being selected from nitrogen and carbon; M is a metal from Group 3 to 11 of the Periodic Table or a lanthanide metal; Eand Eare divalent groups independently selected from (i) aliphatic, hydrocarbon, (ii) alicyclic hydrocarbon, (iii) aromatic hydrocarbon, (iv) alkyl substituted aromatic hydrocarbon, (v) heterocyclic groups and (vi) heterosubstituted derivatives of said groups (i) to (v); Dand Dare donor atoms or groups; X is an anionic group, L is a neutral donor group; n=m=zero or 1; y and z are independently zero or integers such that the number of X and L groups satisfy the valency and oxidation state of the metal M.

Polyolefins

A transition metal complex having the following Formula (A): wherein the monovalent groups Rand Rare &#x2014;R, &#x2014;OR, &#x2014;NRR, and &#x2014;NHR: the monovalent groups R, R, R, Rand R, and the divalent group Rare (i) aliphatic hydrocarbon, (ii) alicyclic hydrocarbon, (iii) aromatic hydrocarbon, (iv) alkyl substituted aromatic hydrocarbon (v) heterocyclic groups and (vi) heterosubstituted derivatives of said groups (i) to (v); M is a Group (3) to (11) or lanthanide metal; E is phosphorus or arsenic; X is an anionic group, L is a neutral donor group; n is (1) or (2), y and z are independently zero or integers, such that the number of X and L groups satisfy the valency and oxidation state of the metal M. n is preferably (2) and the two resulting Rgroups are preferably linked. The complex can be used with optional activator to polymerise olefins
