Abstract: Polyamide 6,12 crystalline fibers, commercially known as Nylon 6,12, were irradiated using gamma radiation and characterised by Infrared Spectroscopy (FT-IR), Raman, Differential Scanning Calorimeter (DSC) and Thermogravimetric Analysis (TGA). The analysis of the data, by using Flory|s Theory and the principles of the Compton effect, allowed establishment of a reaction mechanism to explain how the polyamide chains are modified.

Keywords: gamma radiation; nylon; polyamides.
