Abstract
Results on the methods of obtaining and the properties of ultrahigh-molecular polyethylene (UHMP) are presented. Items made of this material survive rigid performance conditions, unlike for usual grades of the polymer. It was demonstrated that modification of UHMP by introducing ultrafine particles of inorganic materials promotes enhancement of the performance characteristics of the items made of UHMP. Results of investigations in the area of the development of technologies for obtaining items made of the composite materials based on modified UHMP. New rubber-polymer materials based no modified UHMP, butadiene-nitrile, cis-isoprene and divinyl caoutchouc were obtained. Due to extremely low abradability and increased performance resources of the items made of the developed materials under extremal performance conditions, the materials may win broad range of applications in various areas of technology.
