摘要

AbstractPreirradiation grafting of α,β,β‐trifluorostyrene onto poly(ethylene–tetrafluoroethylene) film was studied. The trapped radicals formed upon irradiation were able to induce graft polymerization under appropriate conditions. The influences of the grafting conditions were analyzed kinetically. The grafting rate dependency on the preirradiation dose was found to be of order 0.3, and the monomer concentrations, 1.0. The overall activation energies for this grafting were calculated to be 6.2 × 104and 9.3 × 103J/mol below and above 50°C. The grafting rate was found to be independent of the film thickness, which ranged from 25
