Abstract

Cyclic brush-like polymers were synthesized by tandem organo-mediated zwitterionic polymerization and a grafting-to approach. The cyclic polymer backbone, consisting of poly (N-propargylglycine)(c-PNPG), was synthesized by an N-heterocyclic carbene (NHC)- mediated zwitterionic ring-opening polymerization of N-propargyl N-carboxyanhydride. The polymerization proceeds in a quasi-living manner, allowing access to c-PNPG of well- ...
