OPTICALLY ISOTROPIC POLYCARBONATE FILMS AND A METHOD FOR THEPRODUCTION THEREOF |
| 摘要 |
<p>Injection-molding materials comprised of polycarbonate can be processed into optically isotropic films in a chill roll extrusion method. The optically isotropic films are used as covering films for protecting data carriers (CD- ROMS) from becoming scratched, or they are used as supporting materials for the information layer.</p> |
