L-Aspartic acid, sodium salt (1:2) → Succinimide

Participants

Reaction Steps

The reactions and procedures of this Example were repeated, except that the monomer ratios of ammonium aspartate and sodium aspartate were adjusted (in part A) to produce a 1:2 copolymer of sodium aspartate and succinimide. A solution of this copolymer was titrated to pH 4.0 and ring-closed as above. The resulting terpolymer of sodium aspartate, asparagine, and succinimide had a residue ratio of 0.53:10.97 (asp:asn:suc). This terpolymer also was water-soluble.
