  • Catalyst and method for production of polymers and copolymers of 1-alkenes
    Patent number: 4898847
    Abstract: The supported catalyst for the polymerization of 1-alkenes is obtained by a consecutive depositing on the insert inorganic oxide of silicium and/or aluminium at least one organic compound of aluminium, at least one compound of titanium and vanadium and at least one organic compound of aluminium and/or magnesium. It can be phlegmatized by 0.5-50% w/w of the paraffinic hydrocarbon having melting point 25-150.degree. C., which is coated either together with active components of the catalyst or separately.
