AbstractThe synthesis via copper(I)-catalyzed azide alkyne cycloaddition (CuAAC) of three new monomer derivatives of N-vinyl-2-pyrrolidone (VP) carrying cyclic pyrrolidine, piperidine, and piperazine groups and the corresponding copolymers with unmodified VP is shown. The systems bearing pyrrolidine and piperidine displayed both thermo- and pH-response, which has not been reported previously for a polymer with polyvinylpyrrolidone (PVP) backbone. A broad modulation of the LCST with the copolymer composition and pH was observed in a temperature range 0-100 °C. The polymers carrying piperazine exhibited broad buffering regions and no thermosensitivity.
