From: Direct synthesis of partially ethoxylated branched polyethylenimine from ethanolamine
A 13C{1H} NMR (D2O, 126 MHz) of PEI-1; (B) GPC traces of PEI-1 (dashed) and PEI-1-E obtained from catalyst recycling experiment (red solid line); (C) Relationship between ethylene diamine concentration and resulting N content; (D) Kinetics of polymerization for PEI-1 synthesis: Mn (red circles) and Ð (blue squares) vs reaction time.
