Abstract: Polylactide composite materials with inorganic filler -calcium carbonate which have been modified with epoxidized soybean oil and glycerin have been developed. On the basis of the modular-deformation method of calculation the elastic-plastic properties of the developed polylactide materials and the coefficient of structure are determined. The change of the modulus of deformation, modulus of elasticity, surface hardness, Vicat softening point and thermomechanical characteristics of polylactide composites is rev… Show more

The physicochemical patterns of interactions in the starch-glycerol-epoxidized soybean oil system were studied. 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. The effect of epoxidized soybean oil on the viscosity of glycerin-moist starch systems was revealed. On the basis of IR spectroscopic studies and refractive index values, the existence of interactions between the system components was confirmed. The influence of the nature of the plasticizer on the ability to wet the surface of the plasticized starch was determined using the marginal wetting angle.

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.
