Transition And Organic Metals Composition Catalysts For Addition Polymerization
(AREA)
Abstract
A catalytic component for the polymerisation of olefins is prepared by halogenating a magnesium compound of formula MgR'R" in which R' is an alkoxy or aryloxy group and R" is an alkoxy or aryloxy group or halogen with a tetravalent titanium halide in the presence of a halogenated hydrocarbon, and placing the product halogenated with thionyl chloride or an acid halide in contact with a tetravalent titanium compound.
