Abstract: A 1H NMR and rheological study of host-guest complexation interactions between three -cyclodextrin and three adamantyl substituted poly(acrylate)s, and also between them and adamantan-1-carboxylate and native -cyclodextrin, respectively, is reported. A close correllation between molecular level interactions and macroscopic characteristics of polymer networks in aqueous solution exists. It is found that intra- and intermolecular host-guest complexation between the host -cyclodextrin and guest adamantyl substituents and the length of the aliphatic tether between them and the poly(acrylate) backbone have important roles. Dominantly, steric effects and competitive intra- and intermolecular host-guest complexation are found to control poly(acrylate) isomeric interstrand linkage in polymer network formation. The preparations of five new 3% randomly substituted poly(acrylate)s are reported.
