FIELD: processing of plastic materials, molding of polymers by extrusion for manufacture of round and shaped rod-shaped articles from aromatic polyesters. SUBSTANCE: method for manufacture of rod-shaped articles from aromatic polyesters includes heating of blanks in furnace to temperature equals to polymer glass transition temperature. Then, blanks are additionally heated in container to temperature equals to 0.95-0.98 of the temperature of transition to viscous flow state. Extrusion is effected with drawing ratio of λ = 6-8. EFFECT: higher efficiency. 1 dwg, 2 tbl
