Title:
ホモポリマーから光学素子を作製する方法
Document Type and Number:
Japanese Patent JP4347562
Kind Code:
B2
Abstract:
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.
