Abstract
FIELD: production of frothing polystyrene. SUBSTANCE: polymerization of styrene is carried out in aqueous suspension, polyethylene wax having molecular weight 500-3000 is added into said suspension, wax's quantity being 0.01-1 mass % . Thus prepared beads are impregnated by frothing agent and then are isolated of suspension. Degree of styrene's conversion is 60-100% . EFFECT: improves physical and mechanical properties of the product, improves its processing ability. 1 tbl
