N-VINYLCARBAZOLE POLYMER - Nature
Open Data Verified Data
poly (N-vinylcarbazole) is a colorless transparent or Brown transparent amorphous thermoplastic resin. The carbazole group imparts high thermal stability, water resistance and chemical stability to the resin. The disadvantage is friable. It is insoluble in aliphatic hydrocarbons, mineral oil, transformer oil, castor oil, carbon tetrachloride, ethanol, ether, dilute acid, hydrofluoric acid and so on. And soluble in concentrated sulfuric acid, concentrated nitric acid, tetrahydrofuran and chlorinated hydrocarbons. The relationship between the intrinsic viscosity and the molecular weight of the polymer solution is 7=3.35 × 10-2 M-0. 85. Its electrical properties vary little with temperature and frequency, and there is a certain photoconductive effect in the ultraviolet region. Injection molding is generally possible at 300 °c. Properties of poly (N-vinylcarbazole).

N-VINYLCARBAZOLE POLYMER - Preparation Method
Open Data Verified Data
poly (N-vinylcarbazole) is N-vinylcarbazole obtained by reacting carbazole in a phosphonium oil with acetylene in the presence of a catalyst such as sodium hydroxide, boron fluoride, and aluminum trichloride. It is obtained by bulk, solution, emulsion or suspension polymerization. Emulsion or suspension polymerization is commonly used in industry. The emulsion polymerization is carried out by adding N-vinyl carbazole to an aqueous alkali solution and slowly heating to 120-180 ° C. In the presence of emulsifier and sodium dichromate to polymerize PNVC. Suspension polymerization is carried out using a dispersant (polyvinyl alcohol) and an initiator (azobisisobutyronitrile) at 70-100 °c.

N-VINYLCARBAZOLE POLYMER - Use
Open Data Verified Data
- in terms of insulating materials, poly (N-vinyl carbazole) is mainly used as a high-frequency insulating material, such as capacitor dielectric, switch, cable connection and coaxial cable insulation material, can also be impregnated paper, cotton, glass fiber manufacturing low loss, high temperature and high frequency electrical insulation board, pipe and electrical parts. Its foam has a high insulation, more used for broadcasting equipment. In anti-corrosion, it can be used as a substitute for Mica board and asbestos board, and chemical anti-corrosion equipment components with acid resistance (including hydrofluoric acid), alkali and various fluorides at 120 ℃. Copolymers of N-vinyl carbazole and styrene or acrylonitrile are resistant to boiling water and can also be used to make printed font plates.
- can be used in electrophotography, properties: specific resistivity 1019 Q.cm, the insulation is very good, but less than 400m light irradiation, can occur with the wavelength of the different size of the Light current, PVK hole mobility in 10-5~10-6cm/(V.s).
- In addition, poly (N-vinylcarbazole) may be used as a photoconductive material. Germany, the United States, the United Kingdom and Japan are all produced in small quantities. In China, 2,4,7 ~ trinitrofluorenone sensitizers are also developed and used in combination with polyvinyl carbazole resin according to a certain proportion to obtain light-sensitive and highly sensitive charge transfer complexes, it is used as a light guide material in optical plastic video with good effect. The xerographic plate made of the composite is resistant to flexing, and has a service life and sensitivity higher than that of the general sensitized zinc oxide system.
