Furfural‐based cation‐exchange resins fromN‐vinylcarbazole and its polymer

摘要

AbstractCation‐exchange resins have been synthesized through the condensation ofN‐vinylcarbazole and poly(N‐vinylcarbazole) with furfural in presence of anhydrous AlCl3and subsequent sulfonation of the condensates. The resins have been characterized in respect to their polyfunctionality, exchange capacity, and thermal stab
