Crosslinked poly(methyl methacrylate) was first reacted with ethylenediamine or polyethy-lenepolyamine and then reacted with chloroacetic acid to form hydrophilic poly(methyl meth-acrylamide) resins containing α-amino acetic acid groups. The resins coordinated with Cu2+ were used as chromatographic supports to separate the neutral amino acids. The effect of the chromatographic conditions such as composition of the eluent
flow rate and column temperature on the separation was studied.
