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

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.

Keywords

• Durable properties and structures of composition of polypropylene and polyethylene,Benbery mixer,rotor dispergator
