HIGH DIELECTRIC CONSTANT ORGANIC POLYMER OF ORGANIC DISPERSION TYPE ELECTROLUMINESCENT LAMP

摘要

PURPOSE: An organic polymer having excellent moisture resistance and adhesion and used for an insulation layer or a dielectric layer of electroluminescent lamps to improve dielectric characteristics is provided which is low in production cost and can produce soft films. CONSTITUTION: A ternary copolymer of 2-cyanoethylacrylate, allylyanide and methylmethacrylate in a ratio of 2 : 1 : 1 forms an insulation layer or a dielectric layer of electroluminescent lamps in the form of a film to give the electroluminescent lamps. A process for synthesizing CAM20(a ternary copolymer of 2-cyanoethylacrylate, allylyanide and methylmethacrylate) comprises i) adding 0.16g AIBN(azobisisobutyronitrile) to a 100ml flask, ii) adding 4.7ml allylyanide, 8ml methylmethacrylate(MMA), and 19ml 2-cyanoethylacrylate to the flask, iii) adding 10ml benzene to the flask, iv) reacting the compound in the flask at 70°C.
