FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining polyurethane foam plastics by interaction of A1 compounds, which have reactionable with respect to isocyanates, hydrogen atoms, with molecular weight 400-15000; A2 compounds, possessing reactionable with respect to isocyanates hydrogen atoms with molecular weight 62-399; A362-399; A362-399; A3 of water and/or physical foam-generating agent; A4 auxiliary substances and additives, A5 compounds with at least one semicarbazide with B di or polyisocyanates, selected from the group, including: 2,4- and 2,6-toluylenediisocyanate, 4,4'-, 2,4'- and 2,2'-diphenylmethane diisocyanate and polyphenylpolymethylenepolyisocyanate ("multicore MDI").
EFFECT: obtaining polyurethane foam plastics with reduced release of formaldehyde and with low indices of migration and emission of applied activators and additives.
