To arrive at an economical method of producing water-expanded polymer resin moldings, it is proposed that a monomer component and a cross-linker on an acrylate basis and/or a PMMA prepolymer be used as resin-forming components of a curable mixture, with the weight ratio of the water component to the resin-forming component being at least 1:1.
