A method for the production of a rubber-like polymer is proposed, including the stages of extrusion-drying a rubber-like polymer using an increase in the volume of an extrusion dryer 3 equipped with a spinneret having an opening at its outlet; and hot air drying the rubber-like polymer using a hot air dryer 4, where the water content of the rubber-like polymer at the inlet increases the volume of the extrusion dryer 3 from 6 to 25 wt.%; the F / S die flow rate, obtained by dividing the quantity processed (F) of the rubbery polymer in the volume-increasing extrusion dryer 3 by the orifice area (S) of the spinneret, is from 1 to 15 kg / h / mm; the coefficient profile of the spinneret, obtained by dividing the total length of the edge of the spinneret at the output of the increasing volume of the extrusion dryer by the area of the orifice of the spinneret, is from 1.3 to 4.0 mm; the diameter of the circle describing the die opening is 7 mm or more; the water content of the rubbery polymer at the outlet of the increasing volume of the extrusion dryer 3 is from 20 to 70% based on the water content of the rubbery polymer at the inlet of the increasing volume of the extrusion dryer 3. |
