Abstract:
HIGHLY ACTIVE CATALYSTS FOR THE POLYMERIZATION OF OLEFINS RESULT FROM THE COMBINATION OF AN ORGANOMETALLIC COMPOUND AND A COMPLEX OBTAINED BY REACTING A HALOGENATING AGENT AND A TRANSITION METAL COMPOUND SELECTED FROM THE HALIDES, OXYHALIDES, HALOALKOXIDES, OXYALKOXIDES AND ALKOXIDES OF THE METALS OF GROUPS IVB, VB AND VIB OF THE PERIODIC TABLE WITH A SOLID SUPPORT COMPRISED OF AN OXYGENATED COMPOUND OF A BIVALENT METAL WHICH IS SUBSTANTIALLY ANHYDROUS AND IS SUBSTANTIALLY FREE OF HYDROXYL GROUPS.
Abstract:
The present invention relates to the method of polymerizing olefinic monomers utilizing a solid catalyst composition comprising a solid catalytic complex and an activator, to the resultant high impact resistant polymers, to the method of making such catalytic complex, and to the catalytic complex; said catalytic complex comprising the reaction product of an organic oxygenated compound of a metal of groups Ia, IIa, IIb, IIIb, IVb, VIIa, and VIII of the Periodic Table, an organic oxygenated transition compound of a transition metal of groups IVa, Va, and VIa of the Periodic Table, and an aluminium halide.
Abstract:
Polymerization and copolymerization of olefins are carried out in the presence of a catalyst obtained by reacting in the liquid phase a transition metal compound with a solid support comprised of a divalent metallic hydroxide and then activating the resulting complex with an organometallic compound.
Abstract:
OLEFINS ARE POLYMERIZED AND COPOLYMERIZED IN THE PRESENCE OF A CATALYST CONSTITUTED OF THE REACTION PRODUCT OF ONE OR MORE TRANSITION METAL COMPOUNDS, AND A MACROMOLECULAR COMPOUND CONTAINING CARBON-CARBON DOUBLE BONDS IN ITS MOLECULE AND AN ACTIVATOR WHICH IS A METAL, A HYDRIDE OR AN ORGANO-METALLIC COMPOUND OF METALS OF GROUPS I TO III OF THE PERIODIC TABLE.
