PURPOSE: A multilayer sheet with improved weatherability, processability, and shock resistance is provided to offer the multilayer sheet of 1.5mm or less which is composed of a polymethyl methacrylate(PMMA) layer and a polycarbonate(PC) layer and to be used for the window of a cellular phone, PMP, PDA, and a monitor. CONSTITUTION: A multilayer sheet with improved weatherability, processability, and shock resistance comprises a polymethyl methacrylate(PMMA) layer and a polycarbonate(PC) layer. The multilayer sheet has a double structured layer of PMMA and PC. The thickness of a polymethyl methacrylate resin is 8 ~ 12% of the thickness of the multilayer sheet. The thickness of a polycarbonate resin is 88 ~ 92% of the thickness of the multilayer sheet. The thickness of the multilayer sheet is 0.5 ~ 1.5 mm.
