Polymethacrylate molding materials with high heat deformation temperatures and high stability against thermal collapse

摘要

The present invention polymerizes the methacrylate monomer in the reaction medium so that 70% by weight or more of the polymethacrylate molding material is obtained when the concentration of the methacrylate monomer in the reaction medium is 5 mol / l or more, so that the heat deformation temperature is high and the heat disintegration is achieved. The present invention relates to a polymerization process for producing a polymethacrylate molding material having a high stability against.
