ABSTRACT:
The invention concerns a catalyst for olefin polymerisation, of formula (I) wherein: E is an oxygen or sulphur atom; X is a phosphorus, arsenic or antimony atom; M is a nickel, palladium or platinum atom comprising a non-attributed valency; a is 1 or 2; R1, R2, R3, identical or different can be selected among hydrogen, alkyl, cycloalkyl, aryl, alkylaryl, arylalkyl radicals, the hydroxyl radical, the alkoxide radicals (with 1 to 20 carbon atoms), the groups —C(O)OR′—, —SO3Y; and Z represents a hydrocarbon radical comprising 2 to 3 carbon atoms; R represents a hydrocarbon radical of valency a, provided that at least one of the radicals Z or R bears at least an electroattractive substituent
