Cationic polymerization of oxetan by an acid exchanged montmorillonite clay in the presence of acetic anhydride

Araf Sad Dalil, Mohammed Issam Ferrahi, Mohammed Belbachir


The polymerization of oxetan with acetic anhydride catalyzed byMaghnite- H+ (Mag-H) in dichloromethan (CH2Cl2) as solvant was investigated. Maghnite is a montmorillonite sheet silicate clay that is exchanged with protons to produceMaghnite-H+ [1]. It was found that the polymerization is initiated byMag-H in the presence of acetic anhydride at 250C. The effects of the amounts of Mag-H and acetic anhydride were studied. The polymerization yield increased as the proportions of catalyst and acetic anhydride were increased. The reactions were monitored by gel permeation chromatography and 1H-NMR spectroscopy
