Abstract
A copolymer having an RSV less than 0.6 and a process for its preparation in which ethylene, at least one other 1-alkene and, optionally, an aliphatic or alicyclic polyunsaturated monomer are polymerized in the presence of a catalyst system containing (1) a compound of vanadium, (2) at least one alkyl aluminum halide, (3) an .alpha.-halo, ketoaromatic promoter and (4) a chain transfer agent in which the molar ratio of alkyl groups of the alkyl aluminum halide to halogen atoms is at least 1.5.
