FIELD: polymer materials. SUBSTANCE: invention relates to separating polymer particles consisting of chemically unlike polymers having somewhat elevated or, on the contrary, reduced density ranges. Separation is carried out at least in two steps. In the first step, polymer particles with different density ranges are separated from each other with regard to density. Fractions obtained are separated from separating liquid. In the second step, surface of polymer particles with equal density ranges are additionally processed and, once triboelectrically charged, they are separated electrostatically. EFFECT: enhanced separation efficiency. 14 cl, 3 dwg, 4 tbl
