ABSTRACT OF THE DISCLOSURE This invention describes a low pressure process for the homo- or copolymerisation of olefines containing 2 to 10 carbon atoms in the molecule. In particular, it des- cribes a polymerisation catalyst formed from a compound of a Group IV, V or VI heavy metal (Periodic Table of Mendeleev) and an organic metal compound of a metal of Group I, II or III; said catalyst being supported on an aluminium compound of the formula AlKX(3? - n)-nOH, where X is a halogen atom or an inorganic oxygenated anion, m is the valency of the individual group X, K is the number of the aluminium atoms and n is a number varying from 0.01 to 3. As the melt index of the homo and copolymers obtained by the invention can vary over a very wide range, these polymers are suitable for many types of operations.
