Synthesis of New polymers of Triazole Derivatives

Abstract

Thiatriazole is an important monomer, whereby it have two types of functional groups, amine and thiol. Within the frame of this work the triazole monomer have been prepared from its oxadiazole. Two type of polymers were prepared from this monomer via condensation with terephthaldehyde and succinyl chloride, whereby  the binding units of the resulted polymers are  differs, azomethine and amide respectively.  Infrared spectroscopy and elemental analysis were used to identified the polymers. DTA, TGA and DSC analysis indicate the thermal history of the polymers. It was shown that polymer (1) was more flexibility than polymer (2) due to the lower Tg value due to the presence of azomethene group. The Tg are (138^oC) and (190^oC) respectively. Also the DTA, TGA indicates that polymer (2) have high thermal stability than polymer 1 due the presence of the amide group.
