PREPARATION OF POLYVINYLCARBAZOLE THIN-FILM WITH VAPOR-DEPOSITION POLYMERIZATION

N-vinylcarbazole (NVCz) was evaporated toward a substrate of a glass s lide coated with silver 100 nm thick with the existence of a red-heate d filament. The processes of vapor deposition polymerization (VDP) and annealing were observed with in-situ infrared reflection absorption s pectroscopy. The filament temperature of 2300 K and the substrate temp erature of 266 K were effective to retard the re-evaporation of deposi ted NVCz. After NVCz was deposited on the above conditions and then an nealed at 285 K, the resulting VDP film had a number average molecular weight of 1.1 X 10(4) and a polymer yield of 88%.
