More Information
Summary: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.
