Disclosed is an optical film that comprises certain radiation cured (meth)acrylate binders and, desirably, irregular semicrystalline asymmetric particles.

Optical film for display devices

A novel organic/inorganic hybrid material has been discovered comprising a functionalized silsesquioxane and an organic component having reactive endgroups wherein the organic backbone of the organic component is selected from polyimides, polyquinoxolines, polyether ketones, polyether sulfones, and polyesters. The hybrid materials are useful as films that may be employed as reinforced plastics, lightweight metal replacements, and as coatings.

Organic/inorganic hybrid materials

Epoxy resins which have silicon-containing functional groups along the polymer backbone are prepared by reacting a polyether having non-terminal hydroxy groups with a modifying agent which (i) reacts with hydroxy groups and (ii) which also contains trialkoxysilane groups. The modified resins can be reacted with a silicon oxide precursor to form an organic/inorganic composite. The composites are shown to have improved properties at elevated temperatures.
