Abstract (English):
It has been shown that the main mechanical properties of polypropylene homopolymer and copolymer blends are controlled by their structural characteristics, the structure fractal dimension is the main from them. Since a polymers and, hence, their blends are thermodynamically nonequilibrium solids, then the usage of two order parameters, as a minimum, is necessary for any their property determination. The one order parameter application only gives correct result in this case, when the second order parameter is fixed.
