Applicability of heminal mechanism to description of radiation-induced conductivity of polymers

Numerical calculations of radiation-induced conductivity transitional process under homogeneous and Nable generation of separated ion pairs are carried out for a model dielectric simulating high-pressure polyethylene (HPPE) or polytetrafluoroethylene (PTPE) at the absence of pair overlapping (irradiation low dose). The obtained results are compared with the available experimental data. Additional factor explaining kinetic braking of the pair recombination and the ensuing discription of Langevia mechanism of charge carrier volume recombination is required to correlate the experimental results with the theory of heminal conductivity in HPPE, PTFE and polyprolyelene type polymers. 20 refs., 3 figs., 3 tabs
