Zusammenfassung
Alkoxyamine-functionalized silane functions as a chain transfer reagent in ethylene polymerization catalyzed by cationic palladium diimine complexes, without significant adverse effects in productivity or yield. Under conditions of limited chain transfer by β-hydride elimination, this approach highly selectively results in alkoxyamine-terminated hyperbranched polyethylenes (PEs) and multiple (up to 5) functionalized PE chains per active metal site. Stoichiometric NMR spectroscopic investigations indicate that the first chain transfer generates a saturated chain end, while all following polymer chains are initiated by (functionalized) silyl groups. Alkoxyamine-functionalized hyperbranched PEs obtained by this approach are suitable precursors for nitroxide-mediated radical polymerizations. This allows for harnessing different chain growth mechanisms (catalytic insertion/free radical) for generation of PE–polyacrylate and PE–polystyrene block copolymers.
