Abstract
A new approach to the synthesis of thermoresponsive polyrotaxanes, which is based on the termination of poly(2-ethyl-2-oxazoline) living chains by the end groups of polypseudorotaxane obtained from α,ω-diamino poly(ethylene glycol) 2000 and α-cyclodextrin, is proposed. It is shown that poly(2-ethyl-2-oxazoline) synthesized by cationic ring-opening polymerization interacts with polypseudorotaxane end groups and thus effectively blocks dissociation of the complex in solution. The structure of the synthesized copolymers is characterized in detail by 1Н and 13С spectroscopy, IR analysis, and GPC. It is demonstrated that the aqueous solutions of the synthesized polymers feature the lower critical solution temperature.
