A polymer composition having (i) 0.01 to 50% wt (e.g. 0.05 to 15% wt) of a propylene polymer with a polymeric nucleating agent is disclosed. Preferably, the agent contains vinyl compound units and (ii) a heterophasic propylene polymer which includes less (or no) polymeric nucleating agent than the propylene polymer in (i).

Polypropylene compositions

The present invention concerns polymer compositions and a process for the preparation thereof. The compositions comprise a propylene polymer nucleated with a polymeric nucleating agent containing vinyl compound units, and 0.1 to 10% talc, calculated from the weight of the composition, to reduce shrinkage and to improve stiffness of the composition.
