Abstract
The transport properties of various additives were studied by measuring their diffusion rate and solubility in low density polyethylene (LDPE), a blend of low density and linear low density polyethylene (LDPE/LLDPE), and ethylene vinyl acetate copolymer (EVA) at different temperatures. A correlation was found between the diffusion rate and the fractional free-volume of the noncrystalline phase of the polymer, as well as the specific volume of the diffusant. Deviations from the theoretical expectations were attributed to the different free energies of various physical states of additives.
