Succinimide → Aspartate Succinimide

Participants

Reaction Steps

The procedure was repeated using 2.05 g of MgSO4 heptahydrate (8.33 mmol Mg2+ and SO42−, equivalent to 16.7 mmol each of cations and anions). Upon drying, this is expected to produce about 83.3 mmol of Asp as the ammonium aspartate, with 16.7 mmol as Mg aspartate. In this case, the target upon polymerization was a copolymer of aspartate and succinimide with a 1:5 residue ratio. The product had a residue ratio of about 20% Mg aspartate and 80% succinimide (1:4) and was largely insoluble. The molecular weight as shown by gel permeation was approximately 1500 Daltons.
