A Green Synthesis and Polymerization of N-Alkyl Methacrylamide Monomers with New Chemical Approach

In the present work, we have developed an original method to synthesize and to polymerize N-alkyl methacrylamide monomers with a new chemical approach by using an heterogeneous catalyst "Maghnite Na+" as green and recyclable catalyst in one step with respect to the green chemistry principals. The polymerization of N-alkyl methacrylamide monomers was carried out using an environmentally friendly catalyst, during which the monomers were synthesized at room temperature for 2 h by reacting an amino derivative (heterocyclic and aryl amine) with methacrylic anhydride in presence of "Maghnite H+" a green catalyst in a bulk (without solvent). The undertaken green reaction has yielded 85% of conversion and 100% selectivity of the obtained product, and contributed to substitute former used toxic reactant methacryloyl chloride and triethylamine, frequently used in previous published studies. Infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) spectroscopy 1H and 13C subjected the monomers and polymers structures to confirmation.
