Abstract
A process for the polymerization of olefins using a metal complex of group 3, 4, 5, 6, 7, 8, 9 or 10 of the Periodic Table comprising at least one group C═NR1, C═PR1, C═O, C═S or a heteroaromatic ring system containing at least one atom from the group consisting of N, P, O and S, can be used for controlling the width of the molar mass distribution of the resulting polymers.
