Compositions for producing a rigid polyurethane foam are described, comprising at least one isocyanate component, a polyol component, optionally a catalyst which catalyzes the formation of a urethane or isocyanurate bond, wherein the composition has hydrocarbons having 3, 4 or 5 carbon atoms, hydrofluorocarbons, hydrofluoroolefins (HFO), hydrohaloolefins, oxygen-containing blowing agents and/or chlorohydrocarbons as blowing agent, and also comprises acrylate and/or methacrylate copolymers as foam stabilizers.

Production of polyurethane foam

A process produces a (meth)acrylate ester mixture. The process includes reacting a glycerol formal isomer mixture with an alkyl (meth)acrylate in the presence of a catalyst.
