Polymérisation de monomères organiques dans les plasmas froids—4: Étude des structures de polyéthylènes et polytétrafluoroéthylènes, en particulier par résonance paramagnétique électronique

Abstract

The ethylene and tetrafluoroethylene polymerization in a “cold plasma” leads to polymers with considerable deficiencies of hydrogen or fluorine atoms. With electronic spin resonance, the various kinds of radicals trapped in the macromolecular structure have been detected and in some cases identified and determined. The mechanisms could be partly explained in thermodynamic terms. Irradiation of the corresponding commercial polymers gives some information about degradation processes in the plasma.
