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.
