Procedure

A glass-made reaction apparatus equipped with a thermometer, stirrer, dropping device, nitrogen/air inlet tube and reflux condenser was charged with 400 parts of a triethylenetetramine-ethylene oxide adduct (compound obtained by addition of 10 moles, on average, of ethylene oxide to —NH groups of triethylenetetramine), and the temperature was raised to 90° C. in an air atmosphere. While the reaction system was maintained at 90° C., 30.6 parts of glycidyl methacrylate was added over 1 hour. After completion of the addition, stirring was continued at 90° C. for 2 hours to give a triethylenetetramine-ethylene oxide adduct monomer (triethylenetetramine-EO adduct macromer).
