Abstract

Process for obtaining foamed materials by reaction of polyisocyanates with compounds containing at least two hydrogen atoms reactive with respect to isocyanates, of a molecular weight between 400 and 10,000, in the presence of known blowing agents and, if appropriate, in the presence of compounds containing two hydrogen atoms reactive with respect to the isocyanates, with a molecular weight between 32 and 400, as well as, if appropriate, in the presence of auxiliary foaming additives known per se, characterized in that the polyisocyanates and or the compounds containing at least two hydrogen atoms reactive with respect to the isocyanates, with a molecular weight between 400 and 10,000 are incorporated in the form of redispersible settleable dispersions which contain aminoplast condensates as the dispersed phase.
