Abstract
The invention relates to a method for producing a polymethyl methacrylate plate, comprising the steps of providing a mould comprising at least one gasket which is enclosed between two substantially parallel mould parts, introducing liquid comprising methyl methacrylate prepolymer and/or methyl methacrylate monomer in the mould and enabling polymerization of the liquid methyl methacrylate. The invention also relates to a gasket for use in a mould for producing a polymethyl methacrylate plate.
Claims18
Method for producing a polymethyl methacrylate plate, comprising the steps of:
- A) providing a mould comprising at least two mould parts, each mould part having at least one substantially flat mould surface facing an substantially flat mould surface of an opposing mould part, and wherein said mould comprises at least one gasket, which gasket comprises polymethyl methacrylate, and which gasket is clamped in between said substantially flat mould surfaces of opposing mould parts, such that a mould cavity is defined by said mould parts and said gasket,
- B) at least partially filling the mould cavity by introducing liquid comprising methyl methacrylate prepolymer and/or methyl methacrylate monomer into the mould cavity,
- C) polymerization of the methyl methacrylate prepolymer and/or methyl methacrylate monomer introduced in the mould cavity, such that a polymethyl methacrylate plate, enclosed by said gasket, is formed within said mould cavity, and
- D) removal of the assembly of the gasket and said polymethyl methacrylate plate enclosed by said gasket from the mould parts.
