| Abstract
| - Using a hydroxy-functionalized terpyridine as initiator, a poly(ε-caprolactone) containing oneterpyridine endgroup was prepared by tin octanoate-catalyzed controlled ring-opening polymerization. Theω-hydroxy group of this polymer was subsequently reacted with an isocyanato−ureidopyrimidinone, resultingfor the first time in polymers bearing a metal-coordinating ligand on the one and a hydrogen-bonding uniton the other chain end. Hydrogen-bonded supramolecular dimers were shown to be present in chloroformsolution. The subsequent addition of iron(II) ions resulted in the formation of high molecular weightsupramolecular polymers with novel properties resulting from the combination of both types of noncovalentinteractions in the main chain, as could be shown using capillary viscosimetry and rheometry.
