| Abstract: | We have described an original method allowing us to determine traces of oxygen in organic compounds such as polymers modified through grafting of functions containing oxygen.The method allows us to obtain oxygen contents included between a few hundred ppm and 7 to 8%. It consists in the pyrolysis of the sample, the reduction of oxygen to carbon monoxide and, finally the detection of the latter in an infrared analyzer. |
