Lahrech %J Biointerface Research in Applied Chemistry %D 2011 %I Comporter SRL %X In the present work the ring-opening polymerization of glycidyl methacrylate (GMA) using Maghnite-H+, a proton exchanged montmorillonite clay as initiator is reported. The influences of solvent, weight ratio of initiator/monomer and reaction time on the conversion of monomer and on the molecular weight are investigated. Increasing Maghnite-H+ proportion increases (GMA) conversion and decreases the average molecular weight of resulted polymer. A cationic mechanism for the reaction was proposed. %K Maghnite %K glycidyl methacrylate %K GMA %K ring opening polymerization %U http://biointerfaceresearch.com/wp-content/uploads/downloads/2011/10/5.LahceneIssue5Vol1.pdf
