Abstract (en)
[origin: CA3043543A1] The present invention relates to the use i) of one or more compounds selected from the group consisting of R1R2C=CR3-C(O)-O-R4 (I), R5R6C=CR7-C(O)-O-R8-O-(O)C-R9C=CR10R11 (II), R12R13C=CR14-C(O)-O-(O)C-R14C=CR13R12 (III.) and R15R16C=C-17-C(O)-NR18-R19 (IV.), wherein R1 and R2, R4 to R7 and R9 to R19 independently of one another represent H, a saturated or unsaturated, linear or branched, aliphatic or cycloaliphatic or an aromatic or araliphatic radical having up to 20 carbon atoms which may optionally contain heteroatoms such as N, S or O and which may optionally be substituted, for example by isocyanate-reactive groups, preferably by OH groups, R3 represents H, and R8 represents a saturated or unsaturated, linear or branched, aliphatic divalent radical having up to 20 carbon atoms which may optionally contain heteroatoms such as N, S or O and which may optionally be substituted, for example by isocyanate-reactive groups, preferably by OH groups, and/or ii) of polyester polyols, preferably polyester diols, obtainable by polycondensation of maleic acid, fumaric acid, methacrylic acid or acrylic acid with oligomeric diols such as butanediol, diethylene glycol, propylene glycol, 1,3-propanediol and/or triols such as glycerol having a molecular weight factor per double bond of 150 to 3000, a functionality of 2 to 6, a hydroxyl number of 20 to 800 and an acid number of 0 to 15 in processes for producing polyurethanes, preferably polyurethane foams, for reducing the aldehyde emission of the resulting polyurethanes/polyurethane foams, to a process for producing polyurethanes, preferably polyurethane foams, using one or more compounds of formula IV and to polyurethanes obtainable from this process.
