STUDY AND CHARACTERIZATION OF THERMALLY STABLE POLYAMIDES SYNTHESIZED FROM HETEROCYCLIC MOIETY IN THE MAIN CHAIN
Main Article Content
Abstract
Colored compounds were formed by polycondensation reaction of s-triazine consuming diamines with secondary amine morpholine. The diazotization coupling reaction with α-Naphthol showed dark coloration property. Initially, secondary amines binded with s-triazine at lower temperature and then smoothly proceeded at room temperature and further compiled with coupling product to result out the required series. The inherent viscosities were obtained in between 0.21-0.42 g/dL which was measured by Ubbelohde viscometer. The colored series was identified by several techniques like NMR, IR, and UV spectroscopy. Furthermore, thermal degradation properties were determined by DSC and TGA techniques. The thermal stability was evaluated in the temperature range of 200°C-800°C. The DSC explained about increase in Tg value with an increase in the aromatic contentin between 220-300°C. The obtained series showed excellent thermal stability with their temperature weight loss (10%) around 450°C and 480°C. Synthesized polyamides can be utilized as multipurpose roles in medicine, electronics, aerospace, and advanced structural composites. This paper will briefly review the role of obtained complex which involves processability, stability and performance of the materials.
