✦ Synopsis

The synthesis of a new side-chain polyrotaxane containing dimethyl-8-cyclodextrin is described. The rotaxane side groups are attached via amide functions at a poly(ether-ether-ketone). Some characteristics of the polyrotaxane are compared with those of a corresponding guest model compound. It was found that the glass transition temperature, the solubility in methanol and some 'H NMR shifts are significantly influenced by the non-covalently anchored cylodextrin.

Additionally, it was observed that the non-covalently anchored cyclodextrins could be completely degraded by enzymatic reaction.
