    • There is provided a method of producing a polyvinyl alcohol (PVA) film polarizer having an excellent durability, the method comprising dyeing, cross-linking, stretching, and drying, wherein additives containing phosphorus is inputted into one or more of the dyeing, the cross-linking, and the stretching. In this case, the additives containing phosphorus may be selected from a group consisting of a phosphoric acid, potassium phosphate monobasic, potassium phosphate dibasic, magnesium phosphate dibasic, sodium phosphate monobasic, and ammonium phosphate monobasic. An amount of the additives containing phosphorus in an added solution may be 0.01 to 15 wt %. As described above, when inputting the additives containing phosphorus while producing a polarizer, cross-linking between iodine and a polymer matrix becomes strong due to the phosphorus contained in the additives, thereby producing a polarizer having an excellent durability, and particularly, an excellent thermal stability.
    • 提供了一种具有优异耐久性的聚乙烯醇(PVA)膜偏振片的制造方法,该方法包括染色,交联,拉伸和干燥,其中将含磷的添加剂输入染色,十字 链接和拉伸。 在这种情况下,含磷的添加剂可以选自磷酸,磷酸二氢钾,磷酸氢二钾,磷酸氢二钾,磷酸二氢钠,磷酸二氢铵等。 在添加溶液中含有磷的添加剂的量可以为0.01〜15重量%。 如上所述,当制备偏光片时,当输入含有磷的添加剂时,由于添加剂中含有的磷,碘与聚合物基体之间的交联变得强烈,从而制造出具有优异的耐久性的偏振片,特别是优异的热 稳定性。
