Abstract: DEC 11 1984 Process for the preparation of copolymers consisting of 25-85 % by wt. of ethylene 15-75 % by wt. of at least one other l-alkene and optionally up to 20 % by wt. of a polyunsaturated compound with application of a catalyst system containing a compound of a metal from sub-groups IV-VI of the periodic system and a compound of n metal from groups I-III of the periodic system, in which at least one hydrocarbon group is bound directly to the metal atom via a carbon atom, the polymerization being carried out in the presence of a halogencontaining compound of one of the following groups: a. compounds of the general formula where A is a phenyl or benzoyl group with one or two substituent nitro groups, X is a chlorine or bromine atom, Y is a chlorine, bromine or hydrogen atom or a hydrocarbon group with 1-8 carbon atoms, and Z is a nitrile group, a carboxyl group, an ester group, a hydrocarbyloxyalkylcarboxyl group, a carboxylhalide group, an amide group, a benzoyl group, a carboxyphenyl group, a carboxyhydrocarbylphenyl group, a phenyl group or a phenyldihalogenmethyl group, b. compounds of the general formula where B is a phenyl group which may contain one or two substituent halogen atoms or alkyl groups, or is a thienyl, furyl, pyrrollyl, N alkyl pyrollyl or pyridyl group, which group is bound to the carbon atom directly or via a carbonyl group, X is a chlorine or bromine atom, Y is a chlorine, bromine or hydrogen atom or a hydrocaarbon group with 1-8 carbon atoms, and Q is a phenyl group or a phenyldihalogen methyl group. c. oxalyl chloride or oxalybromide.
