phosphoric add-group and amino-group were introduced onto ethylene-vinyl alcohol(EVA) backbone respectively and the corresponding polyionic complexes (PICs) were obtaind. Viscoelastic spectra show that the crystallization and the hydrophobic interactions of the ethylene units and the backbone of EVA main chains have some contribution in maintaining the mechanical strength
especially the formed PIC. In the H2O- DMF-inorganic electrolyte shielding solvent systems
