✦ Synopsis

Abstraet--A functional water-soluble polymer was prepared by cationic polymerization of 1-(2-hydroxyethyl) aziridine in solution (acetonitrile, dimethylformamide, dichloromethane and toluene) using boron trifluoride etherate (1-5 mol%) as initiator. The polymerization in acetonitrile was studied as a function of time and temperature. It occurred without an induction period. The yield and the viscosity of the polymers increased on increasing the polarity of the solvent, the temperature, and the time. The polymers were characterized by elemental analysis, FT-i.r., ~H-NMR and 13C-NMR spectroscopy.
