ABSTRACT:
A process for producing glass fiber-reinforced, transparent cast sheets comprising impregnating glass fibers with a resin syrup comprising 10 to 50 parts by weight of a copolymer (A) consisting essentially of 20 to 95% by weight of an aromatic vinyl compound and 5 to 80% by weight of other polymerizable monomer, 1 to 40 parts by weight of an aromatic vinyl compound (B), 50 to 90 parts by weight of other polymerizable monomer (C) and optionally 0.5 to 10 parts by weight of maleic anhydride, and casting the resulting mixture.
