ABSTRACT:
The invention is a process of manufacture, and a product manufactured by that process. The process comprises various steps. The steps include charging aspartic acid particles into a process unit and heating those particles to approximately 400.degree.-480.degree. F. As the aspartic acid particles are heated, vacuum is applied to that unit. Water is removed from the aspartic acid to form polyanhydroaspartic acid.
