Abstract

A new dialkyneterminated monomer 23bis4prop2yn1yloxyphenylquinoxaline was synthesized and used in the click reaction with various alkyl dibromides by a convenient onepot procedure to yield polytriazoleetherquinoxalines PTAEQ The weight average molecular weights Mw of PTAEQs were measured by GPC and were in the range of 187×104–241×104 g/mol These polymers exhibited Tg and 10  weight loss temperatures T10 in the range of 177–262 °C and 350–420 °C respectively PTAEQs showed excellent solubility in various polar organic solvents and formed lowcolored and tough thin films via solution casting A series of nanocomposites was prepared from solution blending of PTAEQs with epoxideend capped Fe3O4 nanoparticles Structure and morphology of the prepared magnetic nanocomposites MNCPTAEQs were investigated and the effect of interfacial adhesion between organic and inorganic phases on thermal solubility mechanical and optical properties of composites was investigated The functional sites in the polymer chains were also tested for the removal of toxic metal ions such as Cr3+ Pb2+ Cd2+ Sn2+ Cu2+ and Hg2+ from aqueous solutions either individually or in the mixture
