Abstract
A light-polarizing film comprising a polymer mixture containing a polymer having polyene chains formed by partial dehydrohalogenation of a halogenated vinyl polymer or a halogenated vinylidene polymer and one or more of the polymers selected from the group consisting of acrylate polymers and methacrylate polymers. Said light-polarizing film has excellent heat stability as well as humidity resistance and is useful in various fields including liquid crystal device, optical device, etc.
Claims14
A light-polarizing film comprising a polymer mixture of (a) a polymer having polyene chains formed by partial dehydrohalogenation of a halogenated vinyl polymer or a halogenated vinylidene polymer and (b) at least one polymer selected from the group consisting of acrylate polymers and methacrylate polymers;
- said film having said polyene chains oriented by stretching at least 1.2 times its length and said film having substantially improved heat stability as compared to a similar film absent (b).
