FIELD: polymer materials. SUBSTANCE: invention aims at separating polymer particles with close densities and different chemical nature, such as polyethyleneterephthalate and polyvinylchloride. Mixture is heat treated at 70 to 100 C for at least 5 min to impart particles triboelectric charge, whereupon they are separated using electrostatic procedure. EFFECT: facilitated procedure. 9 cl
