摘要:
The present invention relates to a polyarylate prepared by a method comprising a step of copolymerizing divalent phenol, divalent aromatic carboxylic acid halide and the allyl bisphenol derivative. The polyarylate according to the invention is a novel polyarylate in which various functional groups can be introduced to the main chain of the polymer as well as the terminal of a polymer, and the concentration thereof can be adjusted. These functional groups allow improvement in the adhesion force by chemically bonding with the substrate or protective layer when coated, thus the polyarylate is suitably used for a film or a coating composition.

Disclosed are a negative C-type compensation film and a method of preparing the same. The negative C-type compensation film includes a) a base layer, and b) a polymer layer comprising polyarylate prepared by a method comprising the step of copolymerizing divalent phenols, divalent aromatic carboxylic acid halides, and allyl bisphenol derivatives, the base layer and the polymer layer being sequentially layered. The compensation film is capable of being used for the negative C-type compensation film without a stretching process, significantly reduces the thickness of the compensation film, and has significantly improved interlayer adhesion force in a multilayer structure.

An electrode for treating hard-dissoluble waste water requires high oxygen overvoltage, lowerprice and durability. Conventional electrode can not satisfy all of the above three conditions. The present invention provides an elelctrode capable of satisfying all of the above conditions comprising of novel substrate and novel electrode catalyst. The novel electrode catalyst is a three-element catalyst composed of the oxides of Sn--Pt--Ru, and the novel substrate is a ceramic Ti4O7. Such system satisfies durability, cost and electrode voltage characteristics.

摘要:
A white light emitting device (LED) and a manufacturing method thereof wherein an LED coated with polymeric resin in which organic phosphors are solved dissolved and inorganic phosphors are dispersed creates a white LED, thereby producing an effect of excellent luminance and color coordinate without creating a compatibility problem with the polymeric resin. The present invention creates a white LED with a high luminance and a long service life using polymeric composition containing organic and inorganic phosphors, organic and inorganic combined phosphors and organosilicates, and an epoch making improvement in terms of luminance and credibility without additional process added to an existing element fabricating process, thereby enabling to achieve price competitiveness through cost reduction.
