Synthesis and characterization of dimethacrylate macromonomer using maghnite-h+as an eco-friendly catalyst

The dimethacrylate macromonomer named bis (2-hydroxy-3-(méthacryloyloxy) propyl) fumarate (HMPF) was synthesized by ring opening reaction of epoxide function glycidyl methacrylate (GMA) with maleic anhydride (MA) in presence Maghnite-H+ as a catalyst at room temperature and free solvent. is proton exchanged montmorillonite clay it an Algerian activated sulfuric acid 0,23M. HMPF characterized FT-IR, 1H NMR 13C spectroscopic techniques. A kinetic study carried out to determine the amount (5, 10, 20 30%) which will give abetter yield synthesis reaction.
