SOLID PRECURSOR SYSTEM FOR CATALYTIC olefin polymerization, process for their preparation, SYSTEM COMPRISING CATALYTIC SOLID AND PROCEDURE This precursor olefin polymerization IN THE PRESENCE OF THIS SYSTEM CATALYTIC.

摘要

SOLID PRECURSOR OF A CATALYTIC SYSTEM FOR POLYMERIZATION OF OLEFINS THAT INCLUDES AT LEAST A HALOGENED NEUTRAL METALOCENE OBTAINED FROM A TRANSITION METAL, WHICH IS LINKED AT LEAST WITH A HALOGEN ATOM, AND AT LEAST ONE. METHOD OF PREPARATION OF THIS PRECURSOR Whereby SOLID MIXING COMPOSITE NEUTRO metallocene-based halogen and a compound based on IONIZING AGENT IN A MIDDLE mixed. CATALYTIC SYSTEM INCLUDING A organometallic compound derived from a metal selected from Groups IA, IIA, IIB, IIIA and IVA of the Periodic Table and a precursor solid as already described. METHOD OF POLYMERIZATION OF OLEFINS IN WHICH THIS CATALYTIC SYSTEM IS USED.
