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.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
