Green Polymerization of Vinyl Acetate Using Maghnite-Na+, an Exchanged Montmorillonite Clay, as an Ecologic Catalyst

In this work, the green polymerization of vinyl acetate is carried out by a new method which consists in the use of clay called Maghnite-Na+ as an ecological catalyst, non-toxic, inexpensive and recyclable by a simple filtration. X-ray diffraction and scanning electron microscopy showed that Maghnite-Na+ is successfully obtained after cationic treatment (sodium) on crude maghnite.
