Summary: The metallocenes rac ‐C 2 H 4 (Ind) 2 ZrCl 2 ( 1 ), rac ‐Me 2 Si(Ind) 2 ZrCl 2 ( 2 ), and rac ‐Me 2 Si(2‐Me‐benz[ e ]Ind) 2 ZrCl 2 ( 3 ) efficiently copolymerize propene and 5‐vinyl‐2‐norbornene (VNB). 1 and 2 give a high VNB content and high productivities, whereas 3 gives moderate incorporation. Surprisingly, precatalysts 1 and 2 , which have very closely related structures, showed very different reactivities toward VNB, with 1 having a greater affinity for VNB than for propene. The copolymers are quantitatively converted into polyolefins with polar functionalities.
