FIELD: plastics industry. SUBSTANCE: invention, in particular, relates to extruding solid polymers and may be employed for manufacturing round and shaped cross-section bar articles on the basis of aromatic polyketone for various applications. Essence of invention consists in that polyketone powder, prior to be heated, is shaped into cylindrical stock. The latter is then heated in oven to a temperature constituting 0.95-0.98 melting temperature of polyketone. Hot stock is extruded in heated container heated through extrusion die with stretching degree 1.7-2.8. EFFECT: improved procedure. 1 tbl
