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.
An antifriction polymer material which is a product of hardening a composition consisting of a filler comprising a solid lubricant, fibrous material, metallic powder and friction regulating additives, in an amount of 10-95 wt.% and a binder in an amount of 5-90 wt.%, a mixture of polyphenylenes being used as a binder containing functional groups selected from ketal or acetyl groups, of the formula ##STR10## R.sub.3 and R.sub.4 being identical or different;
