Side chain polyrotaxanes: 2. Functionalized polysulfone with non‐covalently anchored cyclodextrins in the side chains

Abstract

The synthesis of a new side-chain polyrotaxane containing P-dimethyl cyclodextrin rings is described. The rotaxane side groups are attached via amide functions at an aromatic polysulfone. Some characteristics ofthe polyrotaxane are compared with those of a corresponding guest model compound. It is found that the T, value, the solubility in chloroform and acetone, some 'H-NMR shifts and the GPC maximum are significantly influenced by the non-covalently anchored cyclodextrin rings.

Cyclodextrin in polymer chemistry: Kinetic studies on the free-radical polymerization of cyclodextrin-complexed styrene from homogeneous aqueous solution

“…Furthermore, the preparation and polymerization of equimolar cyclodextrin complexes of commercial standard monomers like styrene 1 and methyl methacrylate (MMA have been described. It was also shown that the precipitation polymerization of a cyclodextrin complex of a poorly water-soluble monomer like MMA can be described by kinetic equations similar to those for the classical polymerization in solution [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Cyclodextrins in polymer synthesis: free radical polymerization of cyclodextrin host-guest complexes of methyl methacrylate or styrene from homogenous aqueous solution

“…In our group, we have recently investigated the radical polymerization of cyclodextrin complexed methacryl derivatives and some other types of monomers [5][6][7][8][9][10][11][12][13] . Emulsion polymerization of vinyl compounds using cyclodextrins has also been described [14][15][16][17] .…”

Synthesis and characterization of a polyrotaxane consisting of β-cyclodextrins and a poly(ethylene glycol)-poly(propylene glycol) triblock copolymer

“…Recently, Gibson et al studied solvent-switchable polyrotaxanes utilizing polyurethenes and crown ether [16][17] . Ritter et al studied sidechain polyrotaxanes utilizing CyDs and a polymethacrylate or poly(ether sulfone) as a main chain [18][19][20] . Harada et al investigated macromolecular recognition by CyDs with poly(ethylene glycol) (PEG), poly(propylene glycol) (PPG), poly(isobutylene), and polyesters as a family of polyrotaxanes [21][22][23][24][25][26][27] .…”
