✦ Synopsis

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-2pyrrolidone), poly(N-methyl-N-vinylacetamide), poly(N,N-dimethylacrylamide), poly(2methyl-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.

Polyaniline (PANI) was doped with p-phenolsulfonic acid (PSA) or 5-sulfosalicylic acid (SSA). The PANI salts were blended with poly(N-vinyl-2-pyrrolidone), poly( N-methyl-N-vinylacetamide), poly( N,N-dimethylacrylamide), or poly(2-methyl-2-oxazoline) by solution casting from dimethyl sulfoxide.

The dissolution rates of thin polymer films were measured and compared. Mixtures of various ratios of poly(methyl methacrylate), PMMA, and poly( p-hydroxystyrene), PPHS, were dissolved in methyl isobutyl ketone, MIBK. The polymer solutions were then spun into thin films on silicon wafers and dried.

The thermal decomposition behavior of the miscible cellulosic blends cellulose(Cell)/poly( N-vinyl-2-pyrrolidone) (PVP), Cell/poly(ethylene glycol) (PEG), and Cell/poly(vinyl alcohol) (PVA) was investigated by thermogravimetry. The thermal stability of Cell in the Cell/PVP blends decreased but that
