Title (EN) AN IMPROVED OPTICAL DEVICE HAVING CONTINUOUS AND DISPERSE PHASES
(FR) DISPOSITIF OPTIQUE AMELIORE A PHASES CONTINUE ET DISPERSEE
Abstract: front page image
(EN)An improved optical film having a continuous/disperse phase morphology and a method for making the same is provided. At least one of the continuous and disperse phases comprises a blend of homopolymers which are inter-reacted, as by transesterification. The resulting films exhibit a higher degree of birefringence for a given level of strain than analogous films in which the blend is replaced by a random copolymer.
(FR)L'invention concerne un film optique amélioré à morphologie de phase continue/dispersée, et un procédé de fabrication correspondant. Au moins une des deux phases (continue/dispersée) comporte un mélange d'homopolymères qui réagissent entre eux, par exemple en transestérification. Il en résulte des films présentant un degré de biréfringence supérieur, pour un niveau de contrainte donné, par rapport à des films analogues dans lesquels un copolymère aléatoire remplace le mélange considéré.
