Inclusion complexes of poly(ethylene oxide) with a-cyclodextrin are the key compounds in the synthesis of polyrotaxanes. These complexes prepared in aqueous solutions contain free cyclodextrin, which cocrystallizes with the major reaction product. These complexes dissociate upon dissolution in DMF and DMSO to form cyclodextrin and pseudopolyrotaxanes with a low cyclodextrin content. Polyrotaxane was synthesized with the use of poly(ethylene oxide)alpha,omega-bis-amine as a linear component. The end-groups of the polymer in the inclusion complex were modified by the reaction with 2,4-dinitrofluorobenzene. A procedure was developed for purification of a polyrotaxane with high cyclodextrin content.
