Abstract
Abstract The ring-opening polymerization of 1-benzylazetidine (BA) was investigated in bulk and in acetonitrile. The bulk polymerization of BA proceeded with cationic initiators, such as methyl tosylate and 3-hydroxy-1-propanesulfonic acid sultone (PS), at 60°C, and a white, powdery polymer was obtained. The polymer structure was confirmed by elemental analysis and NMR spectroscopy. The polymerization of BA with PS was assumed to proceed via a zwitterion formed by the addition reaction of BA and PS. The polymerization rate was studied in acetonitrile as a solvent. The enthalpy of activation ΔH∗ and the entropy of activation ΔS∗ for the propagation were determined.
