Side‐Chain Polyrotaxanes with a Tandem Structure Based on Cyclodextrins and a Polymethacrylate Main Chain

Abstract

A new structural type for polyrotaxanes (shown schematically on the right) results from the condensation of an amino-substituted cyclodextrin semirotaxane with the free acid groups of a dicarboxylic acid group in the side chain of a polymethacrylate. The structure of the novel polyrotaxane was determined unequivocally by NMR spectroscopic studies and by comparisons with a cyclodextrin-free model compound.
