In this work the activity of samarium(III) acetate was analyzed as a possible initiator in the ring opening polymerization of 2,2-dymetyltrimethylene carbonate. Polymerizations were carried out under solvent-free melt conditions in ampoules-like flasks, equipped with a magnetic stirrer. The effects of temperature, molar ratio monomer to initiator and reaction time on the polymerization features were analyzed. The results indicate that the samarium(III) acetate initiates the polymerization of 2,2-dymetyltrimethylene carbonate, which proceeds up to high conversion and the polymerization rate is first-order with respect to monomer concentration.
