ABSTRACT:
Disclosed herein are thermoplastic resin sheets having a thermal shrinkage within .+-.0.3%, and a process for producing thermoplastic resin sheets by co-extruding a first thermoplastic resin and a second thermoplastic resin which is nonadhesive to the first thermoplastic resin, into a sheet-like structure so that the first thermoplastic resin is covered on both surfaces thereof with the second thermoplastic resin and then peeling off the resulting outer layers of the second thermoplastic resin B to obtain a sheet of the first thermoplastic resin. The thermoplastic resin sheets obtained in accordance with the above production process have an extremely small thermal shrinkage, undergo an extremely low degree of mechanical strain, and exhibits a little optical anisotropy. Because of the small thermal shrinkage, they may be used in liquid crystal displays (LCDs), poultice or sticker. Because of their little optical anisotropy, they may also be used as supports for plate-like polarizers, coating films for plate-like polarizers or optical recording materials.
