Resumo: | Maghnite- H+ is Algerian montmorillonite sheet alumino-silicate clay, exchanged with protons (H+). This solid non-toxic catalyst was successfully used as cationic catalyst for the polymerization of D,L-Lactid at 100°C. Interactions between Maghnite-H+ platelets and the monomer (D,L-Lactide) were studied by solid state 1H, 27Al and 29Si NMR spectroscopy. The results show that, the mechanism of the reaction involves both Brønsted and Lewis acid sites on Maghnite surface. |
