Abstract
The proposed composition contains from 5 to 98 parts by weight of polyphenylquinoxaline, from 1 to 94 parts by weight of an antifriction filler, from 0 to 40 parts by weight of a reinforcing filler, and from 0.1 to 10 parts by weight of a modifying dopant such as terephthalaldehyde, tetranitrile of pyromellitic acid, metal polyphosphinates or carborane-containing compounds. The antifriction material on the basis of said composition features a low and stable coefficient of friction and provides for the operation of dry-friction assemblies constructed therefrom at temperatures of up to 350.degree.
