Abstract :The measurement of durable properties and structures o] composition is carried out 011 the basis of polypropylene (PP) and polyethylene with low density (PELD), obtained in the mixer "Benbery" and in rotor dispergator. It is shown that regulating the regime of crystallization and content of components in system PPPELD. It is possible to change considerably the physical structure and improve the durable characteristics of composition. It is determined that the improvement of homogeneousness of composition, reaching the rotor dispergator brings to naturally increase of mechanical and electrical durability and longevity. One of the directions of science on physics of polymers is the search of ways the increase of mechanical and electrical durability as well as the heatproofness.
