надвисокомолекулярний поліетилен

The influence of additive nature as well as its ratio on the rheological, tribological and technological properties of blends based on ultra-high molecular weight polyethylene has been determined. The energy costs impact in the polymer blends processing has been studied. It is shown that the rheological and tribological properties of the samples have a complicated dependence, which is determined by inhomogeneity of the system.

By the mixing in the melt of various polyolefins is being obtained the materials of the necessary specific properties which can not be obtained during the synthesis. Due to the wide range of molecular masses, there is a relative gradation of low pressure polyethylene according to their values.

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.
