dc.description.abstractPolymerization of 3-hydroxybenzaldehyde was investigated by oxidative polycondensation (OP) method. No polycondensation reaction was observed both in acidic (in CH3COOH) and organic (in THF) media. Polycondensation was carried out with hydrogenperoxide (H2O2) in an aqueous alkaline medium at 90 degrees C. The product was characterized by H-1 NMR, C-13 NMR, FTIR, UV-vis, and elemental analysis. The number average molecular weight, mass average molecular weight, and polydispersity index values of O-3HBA were found to be 3600, 8000 g mol(-1), and 2.22, respectively. The product (O-3HBA) with reactive aldehyde and hydroxyl group was soluble in most polar organic solvents and was composed of phenylene units. Thermal properties of the oligomer were investigated by thermogravimetric analyses under an air atmosphere. The weight loss of O-3HBA was found to be 5 and 50% at 231 and > 1000 degrees C, respectively. The carboneous residue of the O-3HBA was 54% at 1000 degrees C. (c) 2006 Wiley Periodicals, Inc.
