SIDE-CHAIN POLYROTAXANES .2. FUNCTIONALIZED POLYSULFONE WITH NONCOVALENTLY ANCHORED CYCLODEXTRINS IN THE SIDE-CHAINS

The synthesis of a new side-chain polyrotaxane containing beta-dimethyl cyclodextrin rings is described. The rotaxane side groups are attached via amide functions at an aromatic polysulfone. Some characteristics of the polyrotaxane are compared with those of a corresponding guest model compound. It is found that the T(g) value, the solubility in chloroform and acetone, some H-1-NMR shifts and the GPC maximum are significantly influenced by the non-covalently anchored cyclodextrin rings.
