Abstract
Alkali metal dispersions of particle size 2.5-5m , particularly sodium, are prepared in an inert liquid, particularly xylene, by subjecting the metal to ultrasonic waves while immersed in the inert liquid at a temperature not less than the melting point of the metal. The frequency of the ultrasonic waves is generally between 200 and 500 kilocycles per second. The dispersions are specially suitable for the preparation of organo-metallic catalysts which are used in the polymerization of olefines. The catalysts may be prepared by reacting the metallic dispersion with an alkyl halide, e.g. amyl chloride, in a solvent such as pentane, thereby producing the metal-alkyl compound.ALSO:Alkali metal dispersions of particle size 2.5-5, particularly sodium are prepared in an inert liquid, particularly xylene, by p subjecting the metal to ultrasonic waves while immersed in the inert liquid at a temperature not less than the melting-point of the metal. The frequency of the ultrasonic waves is generally between 200 and 500 kilocycles per second. The dispersions are specially suitable for the preparation of organometallic catalysts which are used in the polymerization of olefines, more particularly butadiene, to form elastomeric polymers. The catalysts may be prepared by reacting the metallic dispersion with an alkyl halide, e.g. amyl chloride, in a solvent such as pentane, thereby producing the metal-alkyl compound. If desired, a portion thereof can be reacted with an aliphatic alcohol, more especially a secondary alcohol such as isopropyl alcohol, to form the metal alkoxide and then treated with an olefine such as propylene. However, the preparation of polymerization catalysts from the metallic dispersions of the invention is not limited to the method described since the dispersions can be used in any of the known methods for preparing organometallic catalysts for use in the bulk or gas phase polymerization of butadiene or other olefines either alone or with other compounds copolymerizable therewith.
