The invention relates to a novel acrylic impact sheet having bullet-resistant properties. The bullet-resistant sheet is composed of a copolymer of methyl methacrylate and a C2-18 alkyl methacrylate, plus impact modifiers that are refractive index matched or mismatched with the polymer matrix. The sheet provides very good bullet resisting performance, with better performance at the same thickness as current products, or the same performance at less thickness, thereby providing a product having better properties and/or less weight. The reduced weight of a bullet resistant acrylic sheet formulation will provide reduced raw material, transportation, and construction costs. Bullet resistant transparent glazing is an especially useful application for the invention. |
