Polyazomethine Class Synthesis, Structural Characterization And Performance Study

In this text, p-aminobenzaldehyde, 3,5-dichloro-4-aminobenzaldehyde and3,5-dibromo-4-aminobenzaldehyde are polymerized using solution polymerizationand electrochemistry polymerization.From solution polymerization, polymers are tokened using MALDI-TOF-MSand IR spectrum. The structure of polymers are confirmed and obtain 2-28 repeatunits of poly(p-aminobenzaldehyde). The tip of polymer molecule still have one-NH₂ and one -CHO. To a certainty condtion, this polymer can polymerization tocreat even more molecular weight.This text introduce electrochemistry method polymerized p-aminobenzaldehydeand it's ramification for the first time, and test felt strength performance, repelcausticity and electricity performance of polymer films. Films from theelectrochemistry polymerization have strong felt strength performance, The film ofpoly(p-aminobenzaldehyde) have stronger combine strength with stainless steel thanepoxy resin combine with stainless steel. Since plating p-aminobenzaldehyde and it'sramification films, erode potential increase greatly, the erode potential ofpoly(p-aminobenzaldehyde) and stainless steel discrepancy about 1.0V.poly(3,5-dichloro-4-aminobenzaldehyde) and poly(3,5-dibromo-4-aminobenzaldehy-de)'s erode potential 0.55V and 0.48V high compare to stainless steel, this shows itsfilms have good repel causticity. From poly(p-aminobenzaldehyde) and it'sramification originated oxidation-reduction potentials compare to inertia electrodeshows they are favorable for conductive. They are hopeful gained application inconductive macromolecule materials.
