Notizen:
Poly(vinyl acetate-C14)(PVA) was adsorbed from a variety of benzene and carbon tetrachloride solutions on swollen and shrunken cellophane film, on glass, and on cellulose acetate film. The surfaces were geometrically simple, permitting mechanical measurements of the areas. Glass, shrunken cellophane, and cellulose triacetate adsorbed equal amounts of PVA. Swollen cellophane, however, adsorbed 40 times as much PVA as shrunken cellophane. Desorption experiments indicated that the high PVA adsorption on swollen cellophane showed the high reactivity of the surface rather than the diffusion of PVA into the cellophane.
