Stretched polystyrene film |
abstract |
(57) [Abstract] [Object] The present invention relates to a syndiotactic polystyrene film, and more specifically to a polystyrene film having excellent flatness after coating, passing through a copying machine, and excellent transparency. Is. [Structure] A film made of a styrene-based polymer having a syndiotactic structure, wherein the degree of plane orientation (ΔP) represented by the following formula on at least one side is −0.04 or less, A polystyrene film having a thickness of 0.06 or more and a difference in birefringence (ΔN) between one surface and the other surface of 0.003 or less. |
