Hochwimmer, Georg; Nuyken, Oskar; Schubert, Ulrich S.

Abstract:

[Cu(I) {6,69-bis(bromomethyl)-2,29-bipyridine}2](PF6) complexes were used as metallo-supramolecular initiators for the polymerization of 2-oxazolines resulting in defined polymers with a central 6,69- disubstituted 2,29-bipyridine unit. The living character of the polymerization was demonstrated with the linear relationship between the weight-average molecular weight M — w and the [monomer]/[initiator] ratio as well as in the synthesis of block copolymers. The metal ions could be removed resulting in uncomplexed polymers with a free central metal binding unit.
