Preparation and characterization of novel energetic nitrogen-rich polymers based on 1,3,5-triazine rings

Abstract

Recently, the demand for new renewable and sustainable polymers, as well as their use as precursors to produce energetic materials, has emerged as a popular and burgeoning area of study. In this study, novel energetic nitrogen-rich polymers based on the 1,3,5-triazine ring were synthesized utilizing standard techniques. Four monomers were created initially: 4,6-dichloro-N-(4-chlorophenyl)-1,3,5-triazine-2-amine (A), 1,1’-bis(4,6-dichloro-1,3,5-triazine-2-yl)-1 H,1’H-5,5’-bitetrazole (B), 2,4,6-trihydrazinyl-1,3,5-triazine (C), N-(4-chlorophenyl)-4,6-dihydrazinyl-1,3,5-triazin-2-amine (D) In the second step, seven novel polymers named CHTA, TBT, TBTH, CTBT, THT, CTC, and TCT were synthesized via polyaddition reactions with monomers. Infra-red spectroscopy was used to characterize the nitrogen-rich polymers that were formed (IR). TGA measurements were utilized to investigate the thermal stability of substances. In addition, SEM and ¹HNMR were utilized to describe the compounds. The results of thermal analysis indicate that TBT, CTC, and TCT are less stable than other nitrogen-rich polymers. The reaction yield for synthesized energetic polymer were 73%, 92%, 67%, 80%, 84%, 72%and 74%for CHTA, TBT, TBTH, CTBT, THT, CTC and TCT respectively.
