The invention relates to catalyst compositions including at least one catalyst compound and at least one continuity additive such as poly-oxo-metal carboxylate compound and their use in the polymerization of olefins. The poly-oxo metal carboxylate compound is represented by the formula: (MQO) n wherein M is a metal from Groups 2 to 14; Q is a carboxylate group having 2-24 carbons; 0 is oxygen and n is an integer between 3 and 25. L'invention concerne des compositions de catalyseur comprenant au moins un composé catalyseur et au moins un additif de continuité tel qu'un composé poly-oxo métal carboxylate, et leur utilisation dans la polymérisation des oléfines. Le composé poly-oxo métal carboxylate est représenté par la formule : (MQO)n, dans laquelle M est un métal des groupes 2 à 14, Q est un groupe carboxylate ayant 2-24 carbones ; O est oxygène et n est un entier entre 3 et 25.
