K-type polarizer and preparation thereof |
摘要 |
A process for preparing a polarizer is described whereby a pre-polarizing article comprising an oriented, vinylalcohol polymer film layer, and an acid donor layer comprising a thermal acid generator, is exposed to radiant energy at a temperature sufficient to effect a partial dehydration of the vinylalcohol polymer to a vinylalcohol/poly(acetylene) copolymer.
