Abstract
Ethylene is (co)polymerised under pressure up to 3000 bar and at above 140 deg. C. in presence of catalyst contg. at least one transition metal deriv. and an organic aluminium deriv., during which at least one organic di- or polycarboxylic acid or anhydride is injected into the reaction mixt. as deactivator, in sufficient amount to deactivate the catalyst. The deactivator is chosen so that the reaction prods. can be left in the polymer
