Abstract
Propene polymn. was carried out in the presence of 2 of the title Zr complexes, giving isotactic site-controlled or weakly syndiotactic chain-end-controlled polymers via highly regioselective 1,2 primary monomer insertion. The two catalysts are believed to be good models of Ziegler-Natta active species, albeit with lower abs. rates of chain propagation and transfer.| File | Dimensione | Formato | |
