Temperature-induced transformations of peroxide radicals formed in polytetrafluoroethylene with γ-ray irradiation
- 1. Japan Atomic Energy Research Inst., Gunma
Description
At 2000C, temperature-induced transformations of peroxide radicals from -CF2CF(OO.)CF2- (radical I) to -CF2CFCF2- (radical 1) and -CF2CF2OO. (radical II) to -CF2CF2 (radical 2) in vacuo, and from I to II in oxygen atmosphere were observed. In these thermal transformations, the evolution of CO2 with a small amount of CO and CF2O was observed. Further, measurements of the heat of crystallization of the treated polytetrafluoroethylene suggest that a reduction of polymer molecular weight occurs during the transformations from I to 1 and I to II
