Amino acids are chiral compounds that make up proteins and play an important role in biochemical processes in living organisms. They are widely used as building blocks in organic synthesis, components of asymmetric  synthesis catalysts, separating agents, etc. To this en, we found that interaction of 1 mol aminoethanoic acid with 1 mol  of allyl xloride, 1 mol of (β-chlor)allyl chloride in an aqueous solution of sodium hydroxide leads to the formation of a new monomer – N-allyl-N-(β-chlor)a­l­lyl­aminobutanedicarboxylic acid (ABA) with a yield of 45%.  When carryng out the polymerization of ABA in an aqueous solution in the presence of ammonium persulfate with an initiator concentration of 4х10^-4–5х10^-3 mol/l, water-soluble polymers with sufficiently high values of reduced viscosity  ([η] = 0.15–0.17 dl/q)  for the indicated amino acid were obtained. It was found that polymerization proceeds along the double bonds of diallyl groups according to the cyclolinear mechanism with a pyrrolidine structure.
