| titleOfInvention | Polyvinyl alcohol polymer film and method for producing same |
| abstract | The present invention aims to provide a PVA polymer film which can be used for manufacturing a polarizing film with high absorbance in a long wavelength region and high polarization degree, and a manufacturing method thereof. The solution is a PVA polymer film having a crystal length of 14.5 to 16.0nm in water. And a method for producing a polyvinyl alcohol polymer film, wherein T represented by formula (I) is represented by 1→2 Drying is performed in a manner of 60 to 75 deg.f. T is 1→2 ={T 1 ×（40－V 1 ）+T 2 ×（V 1 －V 2 ）}/（40－V 2 ） （I）（T 1 The surface temperature (. degree. C.) of the first drying roller, V 1 Represents the volatile component ratio (10-30% by mass) of the film when peeled from the first drying roller, T 2 The average value (. degree. C.) of the surface temperatures of the respective drying rolls from the second drying roll to the final drying roll, V 2 The volatile content ratio (% by mass) of the film when peeled from the final drying roll was expressed. ). |
