In the previous paper, the diffusion coefficients of plasticizers in the polyvinyl chloride fraction of plasticizer, and there were little difference between plasticizers. At lower temperatures, the differences in plasticizer efficiencies appeared. Linearity could be found between logD and 1/T, where D is diffusion coefficient and T is absolute temperature, and activation energies increased rapidly as the plasticizer concentration decreased. By Eyring's theory on diffusion, the activation
