XX is the XXth reference in the list of references. Even today, obtaining a cyclic polymer in pure form remains difficult. This paper discloses a synthetic protocol for a vinyl polymer-type cyclic polymer in pure form. Back to tab navigation Download options Please wait A linear macromolecular rotaxane containing a poly methyl acrylate PMA, M n,NMR axle and a crown ether wheel was synthesized via the terminal modification of PMA with a semirotaxane unit and subsequent linking of the wheel and axle components. The positional change of the wheel from the initial to opposite end on the PMA axle comprised the preparation of pure cyclic PMA via an efficient linear-to-cyclic polymer topological transformation.
