Abstract
The description refers to a process for the production of rigid foam from acrylic and/or methacrylic polymers by the polymerization and foaming of acrylic acid and/or methacrylic acid compounds at high temperature. An oligomer mixture from the group of acrylic acid, methacrylic acid, acrylic acid, methacrylic acid C<1-C<6-alkylester or their mixtures, fluorohydrocarbons, flameproofing agents, peroxide catalysts, cell regulators, foam stabilizers and, if required, softeners and cross-linking agents are polymerized and foamed in a single stage at a temperature below 80 degrees Celsius.
