Abstract
The present study describes a new way for synthesis of methacrylamide (MAM) and it's homologue polymethacrylamide (PMAM) under effect of montmorillonite clay (Algerian MMT). The interlayer cation of montmorillonite clay was exchanged with Na + protons (anionic process). Monomer was successfully synthesized by the condensation of ammonia with methacrylic anhydride in bulk (without solvent) and the polymer with increasing anionic catalyst (Mag-Na+) in Tetrahydrofuran THF. Furthermore, the obtained monomer (MAM) and polymer (PMAM) were characterized and confirmed by Infrared Spectroscopy (FT-IR), 1H nuclear magnetic resonance (NMR) spectroscopy and Thermal properties by thermogravimetric analysis (TGA). The conversion and yield of monomer-polymer increased with the increase of the amount of catalyst “Maghnite-Na+”, the reactivity of the ammonia related to its basicity and the effect of amine substitution with methacrylic anhydride involved electron donor forces of the substitution group.
