Abstract

Procedure for the copolymerization of ethylene with at least one mono-alpha-olefin, in the presence of a saturated hydrocarbon diluent, in which the copolymeric product is significantly soluble, characterized in that it comprises reacting the comonomers with a catalytic composition that is the product reaction of a transition metal complex of general formula Rm MXp with a finely divided inert matrix material having a hydroxylic surface free of adsorbed moisture, where M is a metal from groups IVA to VIA of the Periodic Table, R is a hydrocarbyl or substituted hydrocarbyl group and X is a simply charged or anionic ligand or a neutral monodentate ligand, m being an integer of 2 up to the valency of the metal M and p being 0 or an integer of up to 2, after which a wetting agent is added to the reaction mixture and the diluent is removed from the reaction mixture by steam distillation.
