Syndiotactic polystyrene biaxially stretched film |
| abstract |
(57) [Summary] [Object] The present invention provides a biaxially stretched syndiotactic polystyrene film, and more specifically, a syndiotactic polystyrene film having excellent heat resistance and good handling properties regardless of the film thickness. The present invention relates to a biaxially stretched film. [Structure] A styrene-based polymer having a substantially syndiotactic structure, the orientation ratio obtained by the following formula is in the range of 0.2-1.5, and the heat shrinkage stress at 200 ° C in the width and longitudinal directions is 200 ° C. Dynamic elastic modulus at 10Hz A biaxially stretched film having a quotient divided by 0.01 or less and a dynamic elastic modulus (10 Hz) at 200 ° C. in the width and longitudinal directions of 1.0 × 10 6 dyne / cm 2 or more. Orientation ratio = Ax / Ay Ax: infrared light polarization direction 1222Cm -1 band intensity Ay when matched with the width direction of the film: the infrared light polarization direction when matched with the longitudinal direction of the film 1222Cm -1 Band strength |
