DURABLE PROPERTIES AND STRUCTURE OF COMPOSITIONS OF POLYPROPYLENE-POLYETHYLENE OBTAINED BY DIFFERENT WAYS

Özet

The measurement of durable properties and structures o]composition is carried out 011 the basis of polypropylene (PP) andpolyethylene with low density (PELD), obtained in the mixer"Benbery" and in rotor dispergator. It is shown that regulating theregime of crystallization and content of components in system PPPELD.It is possible to change considerably the physical structure andimprove the durable characteristics of composition. It is determinedthat the improvement of homogeneousness of composition, reachingthe rotor dispergator brings to naturally increase of mechanical andelectrical durability and longevity. One of the directions of science onphysics of polymers is the search of ways the increase of mechanicaland electrical durability as well as the heatproofness.
