Synthesis and chemical modification of new epoxy resins containing alkylaminopyridines

A new series of epoxy resins containing 4-(N,N-dialkylamine)pyridines (DAAP ) functionality was prepared by reaction of 4-aminopyridine or/and aniline with epichlorohydrin. Then, hydroxyl groups in the polymeric chain underwen t a chemical modification with acyl chloride. Modification of the side grou p and backbone of the chain resulted in an enhancement of solubility of the Linear catalyst with catalyzed system and also led to an accelerated acyla tion. Here, acetylation of tert-butyl alcohol was monitored by means of chr omatographic analyses for determining the catalytic power of these polymeri c catalysts. Catalytic activity of the modified linear poly(4-iaminopyridin e-epichlorohydrin-aniline) was found to be more effective than that of DMAP , and catalytic activity of network polymers in a heterogeneous system was found to be somewhat lower than that of any of its linear analogs.
