dc.description.abstract	Theoretical and experimental aspects on association phenomena generated by hydrogen bonding, dispersive and electrostatic interactions in ternary systems consisting of a proton-donor solvent (N,N-dimethylformamide or methanol), a proton-acceptor solvent (water), and a proton-acceptor polymer (polysulfone with different alkyl side chains), are investigated. In this context, binary and ternary thermodynamic interaction parameters are corrected on the basis of different association constants. Numerical values for these constants were evaluated as a function of the system composition, by mathematical simulations. As a result, mathematical simulations allow a good theoretical description of the preferential adsorption in agreement with experimental data.	en_US
