A method for producing a polymethyl methacrylate plate includes the steps of providing a mould that includes at least one gasket which is enclosed between two substantially parallel mould parts, introducing liquid including methyl methacrylate prepolymer and/or methyl methacrylate monomer in the mould and enabling polymerization of the liquid methyl methacrylate. A gasket is used in a mould for producing a polymethyl methacrylate plate.
