FIELD: chemical industry; production of polymeric granulates free of vacuoles. ^ SUBSTANCE: the invention presents a method of production of polymeric granulates free of vacuoles. The method provides for an extrusion of melt of polycarbonate, refrigerating of a produced extrudate and its cutting. Refrigerating is conducted at a speed of less than 50 / sec up to the temperature exceeding vitrification temperature of polymer by 1-20, at which the cutting is exercised. The invention allows to produce polymeric granulates, content of a vacuole in which makes less than 1 vol. %, in particular less than 0.1 vol. %. ^ EFFECT: the invention allows to produce polymeric granulates, content of a vacuole in which makes less than 1 vol. %, in particular less than 0.1 vol. %. ^ 2 cl
