Gelatin-Na-Cellulose Sulfate 사이의 Complex 생성에 관한 연구

다국어 초록 (Multilingual Abstract)

This study deals with the formation of gelatin-Na-cellulose sulfate complex. Investigations were conducted on the influences of pH, mixing ratio, contacting patterns of reactants and reaction temperature for the complex formation as well as on binding features and solubility of the complex formed.
The results were as follows :
1. The complex was formed by the electrostatic forces as gelatin was strongly protonated below the iscelectic point, but above that point formed by hydrogen bond.
2. When the ratio of polycation to polyanion was below 1/3, the complex was soluble, and when the ratio above 1/1 it became insoluble.
3. In case of the back titration of complex which was formed jat acidic pH with NaOH, hydrogen bond increased markedly as compared with that of alkaline pH.
4. In the contacting pattern adding SCS solution to gelatin solution, the turbidity was larger than that of the inverse pattern.
5. The complex formation was promoted following to the degree of NaCI added, and the effects of NaCI on turbidity was remarkably evident around the isoelectric point.
