Abstract (en)
[origin: WO2021122431A1] The invention relates to a method for producing polyurethane foams by reacting the following components: A polyol components, containing A1 40 to 100 parts by weight of polyether carbonate polyol with a hydroxyl number according to DIN 53240-1 (June 2013) of 20 mg KOH/g to 120 mg KOH/g, A2 0 to 60 parts by weight of polyether polyol with a hydroxyl number according to DIN 53240-1 (June 2013) of 20 mg KOH/g to 250 mg KOH/g, and an ethylene oxide content of 0 to 60 wt.%, wherein polyether polyol A2 is free of carbonate units; B B1 a catalyst, and B2 optionally auxiliary and additional substances; C water and/or physical blowing agents, with D di- and/or polyisocyanates, wherein the production occurs at a characteristic value of 90 to 120, characterised in that the production occurs in the presence of 0.01 to 10.00 parts by weight of a component K, in relation to the total of the parts by weight of the component A1 + A2 = 100 parts by weight, and the component K is a compound according to formula (II), wherein R1= represents a substituted or unsubstituted C1-C22 alkyl group which can optionally be interrupted by heteroatoms, a substituted or unsubstituted C1-C22 alkenyl group which can optionally be interrupted by heteroatoms, a substituted or unsubstituted C1-C22 alkoxy group which can optionally be interrupted by heteroatoms, a substituted or unsubstituted C6-C18 aryl group, a substituted or unsubstituted C6-C18 aryloxy group, heteroaryl group, thiols, phosphorous compounds, carboxylates, isocyanates, amines, carbamines, amides or carbamides, R2 = can be the same or different and represents a substituted or unsubstituted C1-C22 alkyl group which can optionally be interrupted by heteroatoms, a substituted or unsubstituted C1-C22 alkenyl group which can optionally be interrupted by heteroatoms, a substituted or unsubstituted C1-C22 alkoxy group which can optionally be interrupted by heteroatoms, a substituted or unsubstituted C6-C18 aryl group, a substituted or unsubstituted C6-C18 aryloxy group, and X = can be the same or different and represents F, Cl, Br or I.
