Resumen
Earlier evidences for the adsorption of a homologous series of alkyl p-hydroxybenzoates onto Teflon are confirmed by direct measurements. The kinetic analysis suggests that the adsorption occurs via two consecutive processes: flat adsorption followed by the solute reorientation at the polymer surface. The adsorption isotherms confirm that the strength of interaction increases with the solute hydrophobicity, An increased wettability of the Teflon surface was also observed to occur parallel to the adsorption, suggesting the presence of some oriented solute molecules which reduce the interfacial tension between the polymer and water.
