The miscibility of five chitosan/tertiary amide polymer blend systems was studied. Based on the optical transparency of the blend and the existence of a single glass transition temperature, chitosan was found to be miscible with poly( N ‐vinyl‐2‐pyrrolidone), poly( N ‐methyl‐ N ‐vinylacetamide), poly( N , N ‐dimethylacrylamide), poly(2‐methyl‐2‐oxazoline), and poly(2‐ethyl‐2‐oxazoline). Fourier transform infrared spectroscopy showed the existence of hydrogen‐bonding interactions between chitosan and the tertiary amide polymers. © 2000 John Wiley & Sons, Inc.
