- 中文摘要: The interfacial properties of the graft polymer, which consists of polyvinyl alcohol with polyvinyl acetate branchings prepared according to the procedure given in the previous papers, have been investigated. No significant difference between the inward and outward form of the graft polymer in interfacial tension has been observed, but remarkable differences in the ability of foming fine droplets and in the stability of the emulsion were found. This seems to be attributable to the existence of two configurational forms of the graft polymer of which the affinity with the oil phase are different from each other. It is conceivable that neither form of the graft polymers has a solubilization power for water insoluble substances. But the effect of substances slightly soluble in water on the viscosity of the polymer solution is dependent on the different configurational conditions of the polymer molecule in solution. This is considered to depend on the intra-action of the polymer molecules, the interaction between the polymer molecules, and the medium into which the substances dissolve.
