 note = {Experimental results of the electrical properties obtained in the course of comprehensive investigation of the water-vapour permeability, diffusion and sorption of organic film-forming materials are summarized. Materials are polyvinyl chloride as specimen. The problem on diffusion was largely concerned with measurements of a diffusion coefficients in system for which it was reasonable to suppose that this coefficient was constant. In the present, this problem is approached by evaluating approximate numerical solutions of the diffusion equation for a number of diffusion coefficients varying in different ways with the concentration of diffusing substance. For instance, the knowledge of the film orientation is needed because the rate of diffusion of vapour into polymer substance is strongly dependent on the amount of orientation of the film and the diffusion process itself causes a change in the orientation. The experimental results obtained are as follows: (1) The relation between the equlibriurn sorption of moisture and the volume resistivity concerning the change of electsical properties due to the moisture sorption of insulating PVC film have been investigated. (2) As the result of this experiment, it should be concluded that the insulated PVC film containing 9% plasticizer is superior., Article, 信州大学工学部紀要 20: 109-118 (1966)},
