Influence of emulsifiers on film formation from cellulose acetate latexes. Modeling approach to the fate of emulsifiers in highly plasticized films. II



Experimental results on the redistribution of sodium dodecyl sulfate in cellulose acetate membranes produced from latexes (Part I) are interpreted in terms of a framework involving both thermodynamic (affinity of the components, composition) and kinetic (plasticizer evaporation rate) parameters. Two situations were examined, corresponding to liquid–liquid and liquid–solid phase separation. The proposed model better accounts for the observed phenomena than more classical views about the fate of emulsifiers.
