Abstract: The invention relates to a process for producing rigid polyurethane foams by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms reactive toward isocyanate groups, in the presence of c) catalysts, and d) blowing agents, where, among the compounds having at least two hydrogen atoms reactive toward isocyanate groups, there is at least one graft polyol present capable of preparation via in-situ polymerization of ethylenically unsaturated monomers in polyether alcohols.
