MEHRSCHICHTIGER OPTISCHER FILM, DER POLYMERE MIT NIEDRIGEN GLASÜBERGANGSTEMPERATUREN (TG) ENTHÄLT |
摘要 |
Multilayer optical films are comprised of materials with glass transition temperatures below room temperature (<30° C.). The high refractive index polymers are unique in that they exhibit mechanical properties similar to other low Tg semi-crystalline polymers, yet have significant birefringence (>0.05) when strain induced oriented. Novel combinations of comonomers for thermoplastics control the rate of crystallinity for improved processability and flexibility, giving the films crease and crumple recovery advantages. |
