Optical compensation film having reversed wavelength dispersion

Disclosed is an optical compensation film made of a solution cast of a polymer blend comprising a nitrated styrenic fluoropolymer and a polyimide. The compensation film is a positive-C plate having reversed wavelength dispersion that is capable of providing an achromatic (or broadband) retardation compensation. The optical film of the...

Multilayer optical compensation film having reversed wavelength dispersion

Disclosed is a multilayer optical compensation film comprising a first layer comprising a positive C-plate material and a second layer comprising a polyimide, as well as polymer compositions and resins and solutions containing said polymer compositions. The optical compensation film has a reversed wavelength dispersion that is capable of providing... Akron Polymer Systems Inc

Optical compensation films based on styrenic fluoropolymer

Disclosed are optical compensation films with exceptionally high positive out-of-plane birefringence. The optical compensation films are based on substituted styrenic fluoropolymers and have positive out-of-plane bireftingence greater than 0.02 throughout the wavelength range of 400 nm<λ<800 nm. The optical compensation films of the invention are suitable for use in optical... Akron Polymer Systems Inc

Method for the preparation of nitrated styrenic fluoropolymers

Disclosed is a process for making nitrated styrenic fluoropolymers having various degrees of substitution. The nitrated styrenic fluoropolymer is capable of providing an exceptionally high birefringence ranging from 0.02 to 0.036. Further, the birefringence can be tuned by varying the degree of substitution (DS) of the nitro group on the... Akron Polymer Systems Inc

Aromatic polyamide films for solvent resistant flexible substrates

A process for manufacturing a display device, an optical device or an illuminating device includes casting a polyamide solution onto a base at temperature below 200° C. to obtain a film, heating the film on the base at temperature sufficient to make the film solvent resistant and obtain a polyamide...
