Abstract (en)
[origin: CA2619498A1] The invention relates to a solid plate consisting of a composition of a transparent polycarbonate with a molar mass of Mw of between 16,000 and 21,0 00 g/mol and an MFR of between 50 and 80 cm3/(10 min) (3000C; 1.2 kg), and transparent polymer particles having an optical density which is different from that of matrix materials. The invention also relates to the use of one such solid plate as a diffuser plate in flat-panel monitors.
