Ultrasonic Irradiation Synthesis and Properties of Copolymers of N,N-Dimethylaminoethylmethacrylate with Chitosan

Multi-responsive Pickering emulsifiers: a comprehensive study on the emulsification–demulsification behavior of modified chitosan-coated Fe3O4 nanocomposites

“…For CS-DMAEMA, compared to CS, the disappearance of the absorption peak at 1650 cm À1 indicates the involvement of -NH 2 groups in the copolymerization reaction. 48 Similar changes are observed in the spectra of CS-DMMA and CS-DMAAE. When compared to CS, the absorption peak at 1745 cm À1 in the spectrum of CS-DMMA represents the characteristic absorption peak of CQO groups.…”
