摘要： A modified polymer which can serve as a raw material of novel reverse dispersion retardation films is provided, the modified polymer having no need to select a plurality of monomers or polymers in order to realize a reverse dispersion and having no problems concerning glass transition temperature or the like in drawing treatment. A polymer having a polyol skeleton as its main chain is caused to react with a compound for modification such as an aromatic carboxylic acid hydride. Through this reaction, a modified polymer in which a chemical group such as an aromatic carbonyl group is bonded to an oxygen atom in a side chain of the polyol skeleton is prepared. For example, polyvinyl alcohols and benzoyl chloride can be used as the polymer and the compound for modification, respectively. The chemical group may be a benzoyl group. When this modified polymer is formed into a film and then subjected to drawing treatment, a retardation film which exhibits a reverse wavelength dispersion characteristic can be obtained.

摘要： A method of manufacturing a polarizer is provided that makes it possible to manufacture a polarizer prevented from curling even when a liquid is brought into contact with a hydrophilic polymer film by being sprayed. A method of manufacturing a polarizer includes a swelling step A for swelling a hydrophilic polymer film 1 by bringing it into contact with a swelling liquid 2, a dyeing step B for dyeing the hydrophilic polymer film 1 by bringing it into contact with a dye liquid 3 containing a dichroic material, and a crosslinking/stretching step C for crosslinking the hydrophilic polymer film 1 by bringing it into contact with a crosslinking liquid 4 and further stretching it. In the method, the contact with the swelling liquid in the swelling step A is carried out in the gas phase by spraying the swelling liquid 2 onto both surfaces of the hydrophilic polymer film 1.
