Abstract
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).
Claims17
