A new class of heterocyclic metallocenes, a catalytic systems containing them and a process for polymerizing addition polymerizable monomers using said catalytic system are disclosed; the heterocyclic metallocenes correspond to formula (I): Y j R"i Z jj MeQ k P l (I) wherein Y is a coordinating group containing a six .pi. electron central radical directly coordinating Me, to which are fused on or more rings containing at least one non-carbon atom selected from B, N, O, Al, P, S Ga, Ge, As, Se, In, Sn, Sb and Te; R" is a divalent bridge between the Y and Z groups; Z is a coordinating group, optionally being equal to Y; Me is a transition metal; Q is halogen or hydrocarbon, substituents; P is a counterion; i is 0 or 1; j is 1-3; jj is 0-2; k is 1-3; and l is 0-2.

L'invention porte sur une nouvelle classe de métallocènes hétérocycliques de la formule (I): YjR''iZjj,MeQkP1 coordination contenant un groupement central à six électrons-pi coordonnant directement Me, auquel sont associés un ou plusieurs groupements contenant au moins un atome non carboné sélectionné dans le groupe constitué par B, N, O, Al, Si, P, S, Ga, Ge, As, Se, In, Sn, Sb et Te; R'' est un pont bivalent entre les groupes Y et Z; Z est groupe de coordination éventuellement égal à Y; Me est un métal de transition; Q est halogène ou substituant d'hydrocarbure; P est un contre-ion; i est 0 ou 1; j est compris entre 1 et 3; jj est compris entre 0 et 2; k est compris entre 1 et 3; et 1 est compris entre 0 et 2. L'invention porte également sur un système de catalyse contenant lesdits métallocènes hétérocycliques et un procédé de polymérisation de monomères d'addition polymérisables mettant en oeuvre ledit système de catalyse.
