## Abstract The structure of poly(aspartic acid) prepared by thermal polycondensation has been studied by means of nmr spectroscopy. The analysis of the ^13^C‐nmr spectra of the polymer at various pH values and comparison with the spectrum of poly(α‐L‐aspartic acid) revealed that the polymer contai
## Abstract The conformation of poly(α‐L‐aspartic acid) was investigated on a sample in which β‐bonds were not detected. CD and ir spectroscopy showed that poly(α‐L‐aspartic acid) passes through a conformational change induced by changes of the degree of ionization that is accompanied by precipitat
