FIELD: polymer materials. SUBSTANCE: method resides in that polytetrafluoroethylene, polyethylene, polypropylene, or polyisobultylene wastes are subjected to thermal destruction at temperatures, respectively, 400-480 C, 380-405 C, 375- 395 C, and 330-350 C in thermal destruction gaseous product flow containing 0.1 to 5.0 vol +ACU- air and +AD4- 0.1 vol +ACU- moisture. Wastes are advantageously ground to particle size no larger than 10 mm. Fine product contains spherical particles 0.1-1.0 mcm in size. EFFECT: simplified technology and reduced process cost. 7 cl, 2 dwg, 2 ex |
