Synthesis and some properties of carbazole modified polyvinylchloride and the cation exchange resin therefrom

Abstract

The chlorine displacement reaction between PVC and N‐methylcarbazole‐3,6‐diamine affords a condensate which is insoluble in all possible solvents of PVC. The overall thermal stability of this condensate is appreciably higher than that of PVC. The dielectric behavior is also significantly different from that of unmodified PVC. Sulfonation of the PVC‐carbazole condensate affords a cation‐exchange resin with SO3H and COOH functional moieties.
