摘要: A TRANSITION METAL COMPOSITION USEFUL FOR POLYMERIZING OLEFINS, WHICH IS FORMED BY THE REACTION OF (1) A MATERIAL INSOLUBLE IN ORGANIC SOLVENT HAVING SURFACE HYDROXYL GROUPS FREE FROM ADSORBED WATER, (2) A TRANSITION METAL COMPOUND HAVING AT LEAST ONE HYDROCARBYL LIGAND, THE TRANSITION METAL BEING SELECTED FROM THOSE OF GROUPS IV-A AND V-A OF THE PERIODIC TABLE OF ELEMENTS, AND (3) A COMPOUND OF A METAL OF GROUPS I TO III OF THE SAID PERIODIC TABLE HAVING AT LEAST ONE HYDROCARBYL LIGAND. THE COMPOSITION IS USEFUL IN THE POLYMERISATION AND COPOLYMERISATION OF OLEFINICALLY UNSATURATED MONOMERS, ESPECIALLY ETHYLENE.
