FIELD: chemistry.SUBSTANCE: invention relates to method of obtaining foam polyurethanes, mainly soft polyurethane polyfoams. Foam polyurethanes are obtained from A1 compounds, containing hydrogen atoms, reactionable with respect to isocyanates, with molecular weight 400-15000, A2, if necessary, compounds, containing hydrogen atoms, reactionable with respect to isocyanates, with molecular weight 62-399, A3 water and/or physical foaming substances, A4, if necessary, auxiliary substances and additives, as, for instance a) catalysts, different from component A5, b) surface-active additives, c) pigments or fire-protective substances, A5 of at least one tin (II) salt of general formula (I) Sn(CHCOO)with x standing for integer number from 9 to 15 and alkyl chain CHbeing branched, and B di- or polyisocyanates.EFFECT: foam polyurethanes have low emission indices and good resistance to ageing.8 cl, 2 tbl |
