Unlike many polyvinylpyrrolidones (PVPs), it offers greater viscosity stability at higher temperatures
and in the presence of salts such as sodium chloride . Unlike sodium polyacrylates, Poly (N-vinyl
acetamide) maintains stability as a function of pH over a wide range from about pH 2-14 .
Moderately soluble in: water, methanol, ethanol and blends of alcohols with water .
