Abstract

PURPOSE: To improve stability to the dryness, humidity and heat by mixing aromatic amine with a polymer, produced by dehydrohalogenating a vinyl halogenide type or vinylidene halogenide type polymer, or its modified body.
CONSTITUTION: To produce a polarizing film, a vinyl halogenide type or vinylidene halogenide type polymer is dissolved in a solvent such as dimethylformamide and, after a dehydrohalogenating agent (secondary or tertiary-amine or amidine compound, etc.) is added, said solution is dehydrohalogenated to obtain a polymer solution with polyene coupling formed; and the solution obtained by adding aromatic polyamine, such as acetanilide into the above-mentioned solution is cast on a glass plate and after the solvent is volatilized, a heat treatment, dehydrohalogenation and heat drawing orientation are carried out successively. In addition, a more stable polarizing film can be obtained by adding phenol (derivative) and the reactant of phenol (derivative) and isocyanate to the solution after the 1st dehydrohalogenation together with aromatic amine.
