Abstract

33The present invention relates to a process for producing viscoelastic flexible polyurethane foams having an air flow value of at least 1 dm/s which comprises (a) polyisocyanate being mixed with (b) polymeric compounds having isocyanate reactive groups (c) optionally chain extending and/or crosslinking agents (d) optionally compounds having only one isocyanate reactive group with a hydroxyl number of 100 to 500 mg KOH/g (e) catalyst (f) blowing agent and also optionally (g) addition agents to form a reaction mixture and convert it into flexible polyurethane foam wherein the polymeric compounds having isocyanate reactive groups (b) comprise 10 to 40 wt% of at least one polyalkylene oxide (b1) having a hydroxyl number of 90 to 300 mg KOH/g based on a 3 to 6 functional starter molecule and a propylene oxide fraction based on the alkylene oxide content of 80 to 100 wt% 5 to 20 wt% of at least one polyalkylene oxide (b2) having a hydroxyl number of 10 to 60 mg KOH/g based on a 2 to 4 functional starter molecule and a propylene oxide fraction based on the alkylene oxide content of 80 to 100 wt% 10 to 50 wt% of at least one polyalkylene oxide (b3) having a hydroxyl number of 10 to 55 mg KOH/g based on a 2 to 4 functional starter molecule and an ethylene oxide fraction based on the alkylene oxide content of 70 to 100 wt% and 0 to 20 wt% of at least one polyalkylene oxide (b4) having a hydroxyl number of 50 to 200 mg KOH/g based on a 2 functional starter molecule and an ethylene oxide fraction based on the alkylene oxide content of 80 to 100 wt% and wherein the fraction of compounds b1) to b4) based on the total weight of polymeric compounds having isocyanate reactive groups (b) is at least 80 wt%. The present invention further relates to a viscoelastic polyurethane foam having an air flow value of at least 1 dm/s which is obtainable by such a process and to the use of such a polyurethane foam for mattresses and cushions.
