Fast neutron activation analysis of glycidyl azide polymers

Abstract

Fast neutron activation analysis technique using 14 MeV neutrons has been applied to analyse nitrogen, chlorine and oxygen content of glycidyl azide polymers (GAP) with Mn around 2100. It has been found that the method is better suited for elemental analysis of GAP than infrared spectroscopy. In fact IR spectral analysis fails to detect chlorine in the polymer when the chlorine content is approximately less than 20%. Oxygen is directly measured by fast neutron activation analysis which is unique.
