FIELD: organic chemistry. SUBSTANCE: mixture of polymeric particles is first subjected to surface treatment with mineral acid or alkali solution, followed by allowing particles to freely fall through electrostatic field, thereby separating them. EFFECT: proposed method is useful for separating plastics of dissimilar types, but consisting of particles comprised within substantially same range of densities. 17 cl, 3 tbl
