ABSTRACT:
Process for preparing a flexible polyurethane foam by reacting a polyisocyanate and two different polyols under foam forming conditions so as to prepare a rigid foam and by crushing the rigid foam so obtained in a direction perpendicular to the direction of rise of the foam. Flexible foams are obtained which do not show a major glass transition temperature between -100.degree. C. and +25.degree. C. and which have an anisotropy of 1.80 to 4.00.
