APPLICATION OF QUATERNARY AMMONIUM SALT AS CATALYST IN THE REACTION OF GLYCIDYL METHACRYLATE WITH CO2

This study is related to the investigation of the characteristics of q uaternary ammonium salt catalyst on the addition reaction of carbon di oxide and glycidyl methacrylate (GMA) to form (2-oxo-1,3-dioxolan-4-yl ) methyl methacrylate (DOMA). Among the salts tested, the ones with hi gher alkyl chain length and with more nucleophilic counter anion showe d a higher catalytic activity. The DOMA monomer was obtained in non po lar solvent like toluene and cyclohexane, while poly (DOMA) could be d irectly obtained in aprotic dipolar solvent such as DMF. In order to f acilitate recovery of catalyst, polymer-immobilized quaternary ammoniu m salt was prepared by copolymerization of styrene (ST), divinylbenzen e (DVB) and vinyl benzene chloride (VBC). The catalyst with 2 wt% of D VB, 25 wt% of VBC and quaternized tributyl amine showed the highest ca talytic activity, and its activity was maintained even up to 10 succes sive experimental runs.
