Etude des interactions des mélanges binaires polymériques : Caractérisation physico-chimique et rhéologique

Abstract

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.
