Notes:
The cyanoethylation of polyvinyl alcohol and the merits of using NaCN as the catallyst are discussed. The application of cyanoethylated PVA to cold water-soluble films is specifically discussed. The use of NaOH catalysis was found to lead to nitrile hydrolysis which resulted in humidity-susceptible films. By using NaCN catalysis, it was found that the reaction temperature and per cent solids could be increased resulting in a decrease in undersirable by-product formation. It was found that films could be cast from cyanoethylated PVA with a degree of cyanoethylation between 5 and 10 mole-% which were readily soluble in cold water and which had physical properties very similar to several commercial water-soluble films.
