Cationic Polymerization of Oxetan by an Acid Exchanged Montmorillonite Clay in the Presence of Acetic Anhydride
The polymerization of oxetan with acetic anhydride catalyzed by Maghnite-H + (Mag-H) in dichloromethan (CH2Cl2) as solvant at 25°C was investigated. The effects of the amounts of Mag-H and acetic anhydride on the polymerization of oxetan were studied. The polymerization yield increased as the proportions of catalyst and acetic an- hydride were increased. The reactions were monitored by gel permeation chromatography and 1 H-NMR spectroscopy.
