Abstract
AbstractA group of poly(N‐vinylcarbazole) pendant polysulfones has been prepared by reacting it with benzene, toluene, p‐chlorobenzene‐ and p‐nitrobenzenesulfonyl chloride and N‐methyl carbazole, 3,6‐disulfonyl chloride by the Friedel Crafts reaction. Carbazole‐based backbone polysulfones have also been prepared by the reaction of N‐methyl carbazole, 3,6‐disulfonyl chloride and biphenyl, naphthalene, anthracene, and carbazole in presence of anhydrous aluminum chloride. The various sulfone polymers, thus prepared, have been structurally characterized by elemental analysis and IR spectroscopy. Detailed analyses of thermal stability, dielectric, and conductivity characteristics have revealed certain significant differences between these two types of sulfone polymers.
