Abstract

The metallocenes rac-C2H4(Ind)2ZrCl2 (1), rac-Me2Si(Ind)2ZrCl2 (2), and rac-Me2Si(2-Me-benz[e]Ind)2ZrCl2 (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
