Abstract
A synthetic reaction to produce [2-(2-aminoethoxy)ethoxy] acetic acid (AEEA) derivatives. This synthetic reaction does not require isolation and purification of intermediates. The AEEA derivatives can be used to synthesize high load polystyrene-polyethylene glycol-like resins having excellent swelling characteristics.
