## Abstract Cohen‐Turnbull diffusion theory is used to develop a model for predicting solvent self‐diffusion coefficients __D__~1~ in nonglassy polymer/solvent solutions. Polymer molecules are envisioned as hindering solvent mobility by reducing the average free volume per unit mass in the system a
