Synthesis and characterization of Nylon3

Nylon3 was prepared through base-catalayzed hydrogen transfer polymerization of acrylamide. The polymer was fully characterized by FTIR, FT-Raman, 1H-NMR, 13C-NMR, DSC, TGA, XRD, MALDI-MS, and end-group analyses. Glass transition temperature, thermal degradation temperature, d-space values, crystallinity, average molecular weights and polydispersity of nylon3 obtained were determined. Initiation, propagation and termination mechanisms of base-catalyzed hydrogen transfer polymerization of acrylamide were proposed using the structural analyses of nylon3 obtained.

Keywords:

Nylon3, hydrogen transfer polymerization, poly b-alanine,
