Polymerization of halogen-substituted olefins with novel catalysts

Claim 1

A PROCESS FOR PREPARING SLID HOMOPOLYMERS OF A HALOGEN-SUBSTITUTED OLEFIN, WHICH COMPRISES CONTACTING, AT A TEMPERAURE OF FROM 0 TO 250* C. AND A PRESSURE OF FROM ATMOSPHERIC TO 10,000 P.S.I.G., A HALOGEN-SUBSTITUTED MONOEMIC ALPHA-OLEFIN HAING FROM 3 TO 8 CARBON ATOMS WITH A DISPERSION IN AN INERT REACTION MDIUM OF SOLID PARTICLES OF A HALIDE OF A METAL SELECTED FROM THE GROUP CONSISTING OF TITANIUM, ZIRCONIUM, HAFNIUM, VANADIUM, NIOBIUM, CHROMIUM, MOLYBDENUM, AND TUNGSTEN WHEREIN SAID METAL IS AT A VALANCE STATE BELOW ITS HIGHEST VALANCE STATE, AND AN ACTIVATOR THEREFOR SELECTED FROM THE GROUP CONSISTING OF ALUMINUM AKYLS, MAGNEDSIUM ALKYLS, ZINC ALKYLS, ALKALI METAL HYDRIDES, ALKALI METAL ALUMINUM BY DRIDES, ALKALI METAL BOROFYDRIDES, ALKYL ALUMINUM HALIDES, ALKYL MAGNSIUM HALIDES AND PHENYL MAGNESIUM HALIDES, AN RECOVERING SOLID HOMOPOLYMERS OF HALOGEN-SUBSTITUTED ALPHA-OLEFINS THEREFROM.
