Versuchsvorschrift

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.
