✦ Synopsis
A new mathematical model is presented for the description of certain types of diluent diffusion (migration) through diluent-polymer systems. The model describes anomalous diluent transport into a container of finite volume, and it incorporates mass transfer limitations at the polymer/extractant interface. The extractant is assumed to diffuse slowly or negligibly into the polymer. The model is applied to experimental data obtained with two plasticizers, di(2-ethyl-n-hexyl) phthalate and benzyl butyl phthalate, migrating from poly(viny1 chloride) to water.
