N2 - The construction of polymer networks through host-guest complexation between the β-cyclodextrin (βCD) substituents of 6A-(1-(2- aminoethyl)amino)-6A-deoxy-β-cyclodextrin 2, 3, and 6% randomly substituted poly(acrylate) (PAAβCDen) and the adamantyl (AD) substituents of 1-(2-aminoethyl)amidoadamantyl 2, 3, and 6% randomly substituted poly(acrylate) (pAAADen) is reported. A 2D 1H NOESY NMR spectroscopic study shows the formation of host-guest complexes by the βCD and AD substituents. This is characterized by a complexation constant, K1 = 3020 ± 60 mol-1 dm3, for 3% substituted PAAβCDen and PAAADen as shown by isothermal titration calorimetry. The viscosity ofa2wt%equimolar mixture of 3% randomly substituted PAAβCDen and PAAADen reaches a maximum at [NaCl] = 0.1 mol dm-3, and the viscosity and the storage and loss moduli (G' and G") increase with the increase in degree of substitution from 2 to 6%.
