Zusammenfassung: | PURPOSE: To provide a synthetic resin molding material which is one called a premix being capable of being subjected to a a heat compression molding process higher in productivity than the casting process and prepared by an easy operation within a short time and can give a molding in which the gloss and transparency of the resin particles in the premix are retained and to produce a molding therefrom. CONSTITUTION: This synthetic resin molding material is obtained by mixing 100 pts.wt. mixture comprising 10-60wt.% acrylic syrup based on methyl methacrylate, 0-85wt.% inorganic filler and 1-85wt.% inorganic-filler-filled resin particles having a degree of swelling in methyl methacrylate of below 2.5 and being insoluble in methyl methacrylate with 0.1-5.0 pts.wt. polymerization initiator. |
