摘要： A process for producing casting molds suitable for use in the ceramic industry and consisting of a polymerized material having minute, open pores and possessing a high degree of mechanical strength and an excellent water permeability. There is formed a castable mixture comprising A. a major amount of a polymer powder composed of spherical particles and having a polymerization catalyst uniformly distributed over the entire surface of said particles, B. an emulsion of at most about 20% by weight of water, based on said mixture; at least one water-insoluble, liquid monomeric or only partially polymerized compound polymerizable to form a rigid polymer and capable of being slightly imbibed by said polymer powder, as the oil phase; and a surface active agent capable of maintaining said emulsion; and optionally C. an accelerator for the polymerization of said polymerizable compound. Said mixture is cast to form a casting mold or a filter for liquid or gaseous media or the like, and then polymerized. Finally, the water can be removed from the pores.
