Abstract

Covalent linkages: Zwitterion-based covalent linkages were observed in cyclic oligomers and in dispersed polymers based on monomers. Addition of acids and bases promoted transitions between monomeric species and the oligomeric and/or polymeric states. Exchange of constituent monomer units in the cyclic oligomers was observed in the solution state, whereas the polymers obtained as precipitates from CH₃CN were not converted to the cyclic oligomers (see scheme).
