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. C.

Composition for antifriction material

An antifriction polymer material which is a product of hardening of a composition consisting of a filler in amounts of 10-95 wt.% and a binder in amounts of 5-90 wt.%, a mixture of polyphenylenes being used as a binder containing ketal and/or acetyl groups of the general formula ##STR1## R.sub.3 and R.sub.4 being identical or different, the fraction with n =2-15 amounting to 4-20% of the binder weight. The proposed antifriction polymer material possesses high heat and thermal resistance of about 350.degree.C and 450.degree.C, respectively, which ensures a stable friction coefficient and a high wear resistance of the material at temperatures of up to 320.degree. C.

Antifriction polymer material

An antifriction self-lubricating material comprising fusible polyimides or polyphenylquinoxalines taken in a quantity of from 5 to 95 percent by weight of the antifriction material, and a filler of molybdenum disulphide modified with phosphorus-containing acids or phosphorus-containing esters, the phosphorus content in the modified molybdenum disulphide being within the range from 0.01 to 2 percent by weight, and the modified molybdenum disulphide being taken in a quantity of from 5 to 95 percent by weight of the antifriction material. The modified molybdenum disulphide employed as the filler imparts improved antifriction properties to the material.
