POLYIONIC COMPLEXES DERIVED FROM POLYVINYL ALCOHOL Ⅰ. PREPARATION AND THEIR SOLVATION BEHAVIOR*
摘要:
Polycations and polyanions of polyvinyl alcohol (PVA) with various substitution degrees were pre-pared by acetalization of PVA with aldehyde derivatives such as p-formylbenzoic acid, glyoxalic acid, p-formyl-benzenesulfonic acid, p-formylpyridine, and p-dimethylaminobenzaldehyde and then neutral-ized or quaternarized with methyl iodide. The corresponding PVA type polyionic complexes wereobtained by mixing the aqueous solutions of these polycations and polyanions. The solvation behaviourof these polyionic complexes were investigated.It was found that the H2O-DMF-NaSCN solvent system is superior to the H2O-DMF-NaBr system for these PVA type polyionic complexes.
