    摘要： An improved method of forming an intrinsic polarizer, referred to as a K-type polarizer, includes stretching a polymeric film a first stretching step. The polymeric film comprises a hydroxylated linear polymer which is converted after the first stretching step to form dichroic, copolymer polyvinylene blocks aligned in the polymeric film. The polymeric film is stretched in a second stretching step while converting the hydroxylated linear polymer. This method produces an improved K-type polarizer with excellent polarizing and color characteristics. For example, the dichroic ratio is higher than 100, the color shift for light passed through the polarizer in a crossed configuration is low, and the absorption of light in the blue region of the visible spectrum is more than one half of the absorption for light in the middle of the visible spectrum.

    摘要： An integrated wet stretch method of making an intrinsic polarizer includes the following steps in order: providing a polymeric film comprising poly(vinyl alcohol) and having an original length; immersing the polymeric film in a first bath comprising a first solution having a pH of less than about 3; uniaxially stretching the first polymeric film in the machine direction thereby forming a stretched polymeric film; removing the stretched polymeric film from the first bath; removing excess first solution from the stretched polymeric film; and uniaxially stretching the stretched polymeric film in the machine direction, at a temperature of at least about 120° C., thereby forming a further stretched polymeric film.
