    Abstract<\/span><\/h3>\n

    In this study, two series of bisoxadiazole polymers were synthesized. The first series was synthesized by convert ethanolic solution of 2,6-pyridine di carboxylic acid in the presence of concentrated H2SO4 to diethyl pyridine-2,6-dicarboxylate (comp.1). Compound (1) was converted to its corresponding di hydrazide (comp.2); this compound reacted with oxalyl chloride in pyridine and N-methyl-2-pyrrolidone (NMP) to obtain P1.\u00a0 (Polymer 1) was converted to P2 by cyclized it in the presence of poly phosphoric acid (PPA) as dehydrating agent to obtain P2 as bisoxadiazole polymer. P3-P7 were synthesized by reacting compound 2 with five different di carboxylic acid in PPA as illustrated in scheme I. These polymers were characterized by FTIR but cannot characterize by 1H-NMR because the synthesized polymers were insoluble in most of known deutrated solvents except P1.<\/span><\/h3>\n

    The second series was P8-P13 these polymers synthesized by reacting (comp.2) with 4-hydroxy benzaldehyde in the presence of acetic acid to give N’2,N’6-bis(4-hydroxybenzylidene)pyridine-2,6-dicarbohydrazide(comp.3),compound 3 converting to4,4′-(pyridine-2,6-diylbis(1,3,4-oxadiazole-5,2-diyl) bisphenol(comp.4) by adding bromine solution in the presence of\u00a0 glacial acetic acid and anhydrous sodium acetate. Compound 4 enter in two path first was reacted with oxalyl chloride to get P8. The second path was<\/span><\/h3>\n

    These polymers were characterized by FTIR and 1 H-NMR except polymer 8 which did not show 1H-NMR results<\/span><\/h3>\n

    Thermal stability studied for (P2-P7) and the polymers that afforded from aromatic di carboxylic acid showed higher stability in comparison with those afforded from aliphatic di acid chloride<\/span><\/h3>\n

    The electro conductivity of (P2-P7) was tested at (50-1MHz), at (25-75 \u0366 C) all these polymers recorded moderate to good conductivity at different temperature. Anti-bacterial activity was screened against Escherichia coli (gram-negative bacteria), Bacillus subtilis and Staphylococcus aureus (gram-positive bacteria), and the fungus candida albicans<\/span><\/h3>\n
