The 8-hydroxyquinoline-5-sulphonic acid, acrylamide, and formaldehyde chemical reactions were sequentially followed to obtain a new copolymer, a multifunctional polymer. The structural properties of the synthesized copolymer were established through the various methods of analysis, such as FTIR spectroscopy, UV-Visible spectroscopy and proton NMR spectroscopy, which confirmed that the functional groups necessary in the main polymer chain were successfully incorporated into the synthesized copolymer. The number-average molecular weight (Mn) and the weight-average molecular weight (Mw) of the copolymer were determined using gel permeation chromatography (GPC). The obtained values revealed that the molecular weight is high with a low polydispersity index (PDI) which showed that the structure of the polymer is uniform and that it can be used in thermally stable polymer matrices. The X-ray diffraction (XRD) analysis has demonstrated that the copolymer was semi-crystalline in nature and scanning electron microscopy (SEM) images indicated a consistent and porous surface morphology. The thermogravimetric analysis (TGA) was used to determine the thermal behavior of the material, and the thermal degradation kinetics were examined by using the Freeman-Carroll and Sharpe-Wentworth methods. The findings proved that the copolymer has high thermal stability. In general, it can be stated that the copolymer synthesized is characterized by high thermal resistance, clear structural and favorable morphological properties, which make it a promising material to employ in sophisticated engineering purposes that demand high thermal resistance and the ability to withstand adverse environment.
