Abstract
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 of a 2 wt % 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%.
