Green synthesis of cationic polyacrylamide composite catalyzed by an ecologically catalyst clay called maghnite-H+ (Algerian MMT) under microwave irradiation

Abstract

In this study, a novel green cationic hydrogel of cationic polyacrylamide composite have been prepared and investigated. The synthesis of green cationic polyacrylamide composite was evaluated for its solu-bility in water. The reactions were performed using acrylamide monomer, solvent, catalyst (clay fin called maghnite) and solution of H2SO4 (0.25 M), with the system under microwave irradiation (160 °C) for 4 min. Major factors affecting the polymerization reaction were studied with a view to discover appropriate conditions for preparation of the composite. The cationic polyacrylamide obtained is the subject of future studies of modification and transformation. The resulting polymer has been character-ized by a variety of characterization techniques, such as: Fourier Transform Infrared Spectra and 1H NMR spectra.
