FIELD: manufacture of rigid foam plastics. SUBSTANCE: composition comprises, wt parts: polyvinyl chloride, 100; methyl methacrylate, 25-40; ammonium carbonate, 10-16; sodium dicarbonate, 8-10; azo-isobutyronitrile, 0.3-1.0; dioctylphthalate, 6-12. Composition makes it possible to cut down foaming time as foam plastic retains compression strength. EFFECT: improved properties of the foaming polymeric composition. 9 ex, 1 tbl
