    Synthesis And Characterization Of L-alanine Based Poly(ester-amide)s
    (Oum-El-Bouaghi University, 2016) Abbes, Marwa; Salhi, Slim; Delaite, Christelle; Abid, Souhir; El-gharbi, Rachid
    Novel biomaterials L-alanine based poly(ester-amide)s (PEAs) differing in the amide/ester ratio have been directly synthesized by direct melt copolycondensation of Adipic acid, L-alanine and various aliphatic and heterocyclic diols. PEAs were systematically characterized with intrinsic viscosity, FTIR, 1H-NMR, 13C-NMR, DSC and SEC measurements. The resulting copolymers are amorphous and present increasing glass transition temperatures at increasing L-Alanine contents. L-Alanine-PEAs proved to be materials having high molecular weights that could reach 41800 g/mol.
