A flexible substrate with a high optical transparency (&#x3e;80% from 400 to 750 nm) that is retained after exposure to 300&#xb0; C., near-zero birefringence (&#x3c;&#xb1;0.001), and a relatively low CTE (&#x3c;60 ppm/&#xb0; C.) is disclosed. The substrate may be manufactured as single layer, polyimide films and as a multi-layer laminate comprising a polyimide layer and a thin glass layer. The polyimides may include alicyclic dianhydrides and aromatic, cardo diamines. The films formed of the polyimides can serve as flexible substrates for optical displays and other applications that require their unique combination of properties.

Thermally stable, flexible substrates for electronic devices

A liquid crystal block copolymer comprising at least one liquid crystal polymer block comprising a polymer of diethylene glycol bis(4-hydroxybenzoate) and diphenyl 2,6-naphthalene dicarboxylate and at least one non-liquid crystal polymer block.

Liquid crystal block copolymer and methods of making and using the same

Some embodiments include compositions and/or methods related to optical compensation films. More particularly, some embodiments can include brominated polystyrene compositions, and/or methods for their preparation, suitable for forming optical compensation films. In some embodiments, suitable brominated polystyrene compositions, and/or methods for their preparation, can include aromatic rings having one or more acyl moieties.
