FEATURES OF STARCH MODIFICATION FOR THE CREATION OF POLYMER COMPOSITES

Abstract

The physicochemical regularities of interactions in the starch-glycerol-epoxidized soybean oil system under the influence of ultrasound were investigated. On the basis of rheological curves, the effect of plasticizers on the viscosity of glycerin-starch systems was revealed, depending on the shear rate, time of exposure at temperature, and the nature of starch. On the basis of IR spectroscopic studies, the existence of interactions between the components of the system was confirmed. With the help of moisture absorption, the influence of the nature of the plasticizer on the hydrophilicity of the modified starch was determined.
