In the previous paper, the diffusion coefficients (D) of plasticizers in the polyvinyl chloride compounds were reported, for the plasticizers, TCP, DOP and DOA, over the range of 20-120°C, and 20-60 percent plasticizer. In this paper, the relations were examined between D and flex temperatures and volume resistivities of the compounds. The reciprocal of flex temperatures (Tf°K) is proportional to w
2, where w
2 is weight fraction of resin. If D was measured at over 100°C, linearity was found between 1/Tf and log D, but not linear at lower temperatures, and at 20°C, there seemed to exist a certain general relationship between them. A linear relationship, common to all plasticizers tested, was found between log (ρw
2) and log D, where ρ is the volume resistivity of the compound.
