Polypropylene and polyethylene terephthalate films were immersed in pure triglycerides or fatty acids for a range of times. They were analyzed for the amount sorbed to determine the relative importance of fat chemical configuration and cohesive energy density (CED) on sorption order and amount. Structure affected the order of sorption (palmitic > oleic > linoleic acids or triglycerides) while CED differences and the fatty components determined compatibility. The amount of the CED differences affected the relative solubilities of fatty components in the polymers. The Hildebrand equation for heat of mixing gave values for components in the same order as the experimental results had indicated.
