Synthesis and characterization of imine polymers containing aliphatic etoxy silane group

A series of polyaldehyte were synthesized by oxidative condensation reaction of 4-hydroxybenzaldehyte, 3,4-dihidroxybenzaldehyte, 2-hydroxybenzaldehyte, o-van and 2-hydroxy-1-naphthaldehyte. Polimers were synthesized from this polyaldehytes. Then, graft imine polymers obtained by adding 3-(aminopropyl)-triethoxysilane to this polymers. Sodium hypochlorite (NaOCl) used as oxidant. All of the synthesized polyaldehytes and polyimines were performed solubility tests in toluen, ethanol, methanol, n-hexane, acetone, THF, chloroform, DMF and DMSO. All compounds were characterized by FT-IR, UV-Vis, 1H-NMR, 13C-NMR and XPS spectrums. In addition, thermal properties of properties of the synthesized compounds were determined in solution forms in DMSO. Fluorescence measurements were carried out in various concentrated solutions to determine the optimum concentrations to obtain the maximal PL intensities. Conductivity properties of polymers were search. The number average molecular weight (Mn), weight average molecular weight (Mw) and polydispersity index (PDI) values of the synthesized compounds were determined by the size exclusion chromatography (SEC). SEM images of the synthesized polymers were obtained to look at surface morphology properties.
