Abstract:
    Disclosed is a method of producing homopolymers of ethylene or copolymers of ethylene with other olefins or mixtures thereof by polymerization in suspension in the presence of catalyst systems. Used as catalyst systems are those which contain, as active components, a) a finely divided support material treated with trialkyl aluminium, b) a metallocene complex, c) an open-chain or cyclic aluminium oxane compound and d) an alkali-metal alkyl or alkaline-earth alkyl or mixtures thereof.
