FIELD: compositions which are used in details of friction units operating at temperature higher 300 C and at load higher 20 MPa at dry friction conditions. SUBSTANCE: antifriction polymer composition comprises oligoimide having tail amide groups as binder; graphite together with yttrium oxide is used as filler. Said composition comprises, mas.%: oligoimide having tail imide groups, 70-40 %; artificial graphite, 29-58 %; yttrium oxide, 1-2 %. Method for production of proposed material is simplified by heat treatment of binder being preliminary converted into powder state. Heat treatment of the binder takes place at 180-200 C till oligoimide with tail imide groups is prepared. EFFECT: increased resistance of desired material to affection of high dynamic loads, simplified the method. 4 cl, 2 tbl
