Abstract

Blends based on isotactic polypropylene (PP) and synthesized ultrahigh molecular weight polydecenes (PDs) with different molecular weights are obtained. Their structure, thermophysical, deformation, and rheological properties are studied. It is shown that the differences in the molecular structure of PDs are the main factor determining the phase structure of the studied blends. The addition of PD changes the thermophysical and deformation properties of PP. Nuclear magnetic resonance (NMR) studies have shown that polymeric materials become more fusible and the structure of amorphous regions changes with an increase in the content of PD. The molecular characteristics, viscosity, and quantitative content of PD determine the rheological behavior of the studied blends.
