发明名称 ACRYLIC SHEET HAVING UNIFORM DISTRIBUTION OF COLORING AND MINERAL FILLER BEFORE AND AFTER THERMOFORMING
摘要 The present invention is drawn to a composition and thermoformable sheets and articles made therefrom. In the present invention, ranges of chain-transfer agents, thixotropic agents, and mineral filler content are balanced to minimize migration or maldistribution of coloring matter and mineral filler during curing of methyl methacrylate in a syrup and also during subsequent heating and deformation in thermoforming, to achieve constancy of impact resistance and improve stability of patterns even in deformed portions of formed sheets.
