Abstract
An explanation for wall slip in polymer solutions is given from a thermodynamic point of view. Due to flow induced diffusion, a slip film at the wall consisting of pure solvent can form if a dimensionless number exceeds its critical value. The general conclusions agree qualitatively with experimental findings of others.
