ABSTRACT:
Polymerization or copolymerization of the starting monomers is carried out in a hydrocarbon medium in the presence of a catalyst containing an alkylaluminium chloride compound, a trialkylvanadate and an alkoxyderivative of titanium, or zirconium, or hafnium. The method of the present invention makes it possible to considerably increase the polymerization rate and degree of conversion in the preparation of polymers and copolymers of higher .alpha.-olefines. The resulting polymers of higher .alpha.-olefines have a stereoregular structure with a high degree of crystallinity which is manifested in an increased melting point of the resulting polymer.
