| titleOfInvention | Polyvinyl alcohol polymer film and method for producing same |
| abstract | The present invention provides the following formulas (I) and (II): Δn(MD) Ave ≤ 1.3 × 10 -3 (I) Δn(TD) Ave ≤ 1.3 × 10 -3 (II) [wherein Δn( MD) Ave represents a value obtained by averaging the birefringence in the machine flow direction of the PVA polymer film in the film thickness direction, and Δn(TD) Ave represents the birefringence in the width direction of the PVA polymer film in the film thickness direction. represents a value averaged by ]. Such a PVA-based polymer film can be stretched at a high magnification without causing breakage even when a method of stretching to a relatively high stretching ratio is employed at the time of dyeing or when a relatively high stretching temperature is employed, whereby a polarizing film, etc. The stretched film of can be produced with good workability, high yield, low cost, and good productivity. |
