ABSTRACT OF THE DISCLOSURE 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 Image , where n = 2 - 500, Image , Image , Image , Image , Image , Image , where m = 1-4; R3 and R4 + Image , Image R3 and R4 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° and 450°C, respectively, which ensures a stable friction coefficient and a high wear resistance of the material at temperatures of up to 320°C.
