    Abstract: Polyurethane foams are new when obtained by reaction of polyisocyanates with isocyanate-reactive components including by weight a combination of (A) acrylate polyols of molecular weight 1500-15000 (10-60%); (B) polyetherpolyols of molecular weight 2500-8000 containing below 35 wt.% ethylene oxide-rich polyetherpolyols (20-60%); and (C) polyols of molecular weight 400-2499 (1-35%). Independent claims are also included for (i) the use of acrylate polyols in the production of viscoelastic polyurethane flexible foams; and (ii) the above preparation for the novel polyurethane foams.

    Abstract: A process for preparation of a polyurethane foam of improved long term stability by reaction of (a) polyisocyanates with (b) compounds with at least two H atoms reactive to isocyanate groups, and (c) inhibitors, where the inhibitor is a polyester containing at least one catalytically active amino group is new. An Independent claim is included for a polyurethane foam obtainable as above.
