摘要：
A transparent sheet having improved optical properties is disclosed. The sheet that features a deviation angle αε (min) according to DIN 52305-A-AS of ≦2.0 and a refracting power Dε (min) according to DIN 52305-A-AZ of ≦0.05, is prepared by extruding a molding composition comprising linear (co)polycarbonate having weight average molecular weight of 25,000 to 31,000.
