Polyrotaxanes are molecular entities in which many rings are threaded onto a polymer chain with attached stopper groups hindering the rings from dissociation. Polyrotaxanes were synthesized from isoprene, styrene and cyclodextrins through a one pot reaction in water similar to an emulsion polymerization. The product can be isolated simply by heat filtration. Slide-ring gels are obtained by cross-linking of the threaded cyclodextrins using diisocyanates.
