Polarizing film made of semicrystalline polyolefine. |
摘要 |
<p>Process for the manufacture of a polarizing film by drawing a polymer film containing a dichroic dye at a temperature above the glass transition temperature of the polymer, the polymer film consisting mainly of a semi-crystalline polyolefine and being drawn at a temperature below the crystalline melting point of the polyolefine, the dye being present in liquid form at that drawing temperature, and a polarizing dye-containing polyolefine film having a dichroic ratio of at least 15.</p> |
