dc.description.abstractNew oligo(polyether) ligands with Schiff base type were synthesized by the reaction of diethyleneglycol bis(2-aminophenyl ether) and triethyleneglycol bis(4-aminophenyl ether) with oligosalicylaldehyde (OSA), OSA was synthesized from the oxidative polycondensation of salicylaldehyde (SA) with air in an aqueous alkaline medium at 90 degreesC. The products were characterized by H-1-NMR. C-13-NMR, Fr-IR, UV-Vis and elemental analysis. The number average molecular weight, M,, mass average molecular weight, M-w, and polydispersity index values, PDI, of OSA, graft oligo[1,5-di(N-2-oxyphenyl-salicylidene)-3-oxapentane] (compound 4) and graft oligo[1,8-di(N-4-oxyphenyl-salicylidene)-3,6-oxaoctane] (compound 5) were found to be 1690 g mol(-1), 5150 g mol(-1), 3.05, 1100 g mol(-1). 5400 g mol(-1), 4.90 and 1100 g mol(-1). 5600 g mol(-1), 5.01, respectively. TG and DTA analyses were shown to be stable of oligo(polyether) ligands with Schiff base type against thermo-oxidative decomposition. The weight loss of oligo(polyether) ligands with Schiff base type (compounds 4 and 5) were found to be 52 and 56% at 1000 degreesC, respectively. (C) 2002 Elsevier Science B.V. All rights reserved.
