A CATALYST COMPOSITION AND METHODS FOR ITS PREPARATION AND USE IN A POLYMERIZATION PROCESS

摘要

THE PRESENT INVENTION RELATES TO A CATALYST COMPOSITION AND A METHOD FOR MAKING TH CATALYST COMPOSITION OF A POLYMERIZATION CATALYST AND A CARBOXYLATE METAL SALT. THE INVENTION IS ALSO DIRECTED TO THE USE OF THE CATALYST COMPOSITION IN THE POLYMERIZATION OF OLEFIN(S). IN PARTICULAR, THE POLYMERIZATION CATALYST SYSTEM IS SUPPORTED ON A CARRIER. MORE PARTICULARLY, THE POLYMERIZATION CATALYST COMPRISES A BULKY LIGAND METALLOCENE-TYPE CATALYST SYSTEM.
