FIELD: chemistry of polymers, foams.
SUBSTANCE: invention relates to foams prepared from polyvinyl chloride nanocomposites comprising polyvinyl chloride, inorganic laminated silicates dispersed on polyvinyl chloride mixtures and foam-forming agents. Foam shows the excellent mechanical strength and incombustibility being even at low specific density. Foam shows high effectiveness for foam formation being even with small amount of foam-forming agent and provides preparing the microcellular structure having relatively smaller size of cells as compared with usual foam.
EFFECT: improved and valuable properties of foam.
