With L-glutamic acid as raw materials, N-carboxy-L-glutamic acid-benzyl-anhydride (BLG-NCA) was synthesized by triphosgene.
Introduction Poly-l-glutamic acid (PLGA) is one of the more currently studying poly amino acids materials.
Molecular chains of PLGA have carboxyl side chain of higher activity, it is easy to generate stable complexes with combination of drugs and some are biodegradable in a kind of ideal body of medical polymer materials.

Introduction With the development of materials science, new composite materials with high strength and light mass have come into being, and the materials of arch have been constantly updated.
Because of the superb properties of high strength and high temperature resistance, FGMs (functionally graded materials) are ideal materials for preparing structural elements used in aerospace, nuclear reactors and other high temperature environments.
Assuming that the material of the FGM arch is thermal elastic, the constitutional relationship of the material can be written as
