Zusammenfassung:	PURPOSE:To obtain an artificial marble excellent in heat resistance and appearance, by adding an inorganic filler of specified properties and a curing agent to a polymerizable syrup derived from a methacrylate ester and a monomaleimide. CONSTITUTION:A polymerizable syrup is prepared by using a monomer mixture based on a methacrylate ester (e.g., methyl methacrylate) and monomaleimide (e.g., N-methylmaleimide) as a starting material. To 60-150pts.wt. polymerizable syrup, 40-85pts.wt. inorganic filler essentially consisting of a hydrated inorganic filler having an average particle diameter of 0.5-60mu and a dehydration initiation temperature as determined by DSC at a temperature rise rate of 20 deg.C/ min>=250 deg.C (e.g., aluminum hydroxide) and a curing agent for the syrup (e.g., benzoyl peroxide) are added. The obtained mixture after thorough mixing is cast into a mold and cured to obtain the purpose heat-resistant artificial marble.
