Résumé:
The purpose of this work is to carry out a study on a binary mixture of polymer in order to
combine the characteristics of the two polymers namely sodium alginate and
hydroxypropylmethylcellulose. This association will result in the formation of a viscous mixture.
Several binary mixtures were prepared at different ratios for which we studied the effect of
varying pH and ionic strength. These mixtures will be the subject of a physicochemical and
rheological characterization in order to evaluate the effect of pH and ionic strength on the
properties of the different polymeric mixtures considered.
