Abstract
Abstract Monolayers of two samples of polypropylene containing grafted methyl acrylate branches have been studied at different temperatures. Spreading enthalpies and entropies were deduced by plotting values of surface pressure versus temperature at different values of the area. From the values of such thermodynamic properties we conclude that the macromolecules lie rigidly at the surface with considerable cohesive energy between the monomeric segments.
