calcium carbonate

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 revealed.

The compositions of ultra highmolecular polyethylene with the polymers of different structure and low-molecular additions are discovered. The degree of blends homogeneity on the basis of UHMPE depending on the structure and nature of components and their influence on physical and mechanical properties is studied. Досліджено композиції надвисокомолекулярного поліетилену з полімерами іншої будови та низькомолекулярними доданками. Вивчено ступінь однорідності сумішей на основі НВМПЕ від складу та природи компонентів та вплив їх на фізико-механічні властивості.  

A quantitative structural model of particulate-filled polymer composites impact toughness, based on the fractal analysis ideas, was offered. The model demonstrated good correspondence with the experimental data. It has been shown that the action of nanofiller as nucleator, resulting in crystallinity degree and amorphous phase structure change, exert the main influence on impact toughness value.
