Radiation grafting of α,β,β‐trifluoroethylenesulfonyl fluoride onto low‐density polyethylene film by simultaneous irradiation method. I. Kinetic study of simultaneous‐irradiation grafting

摘要

Abstractα,β,β‐Trifluoroethylenesulfonyl fluoride (TFESF) was grafted onto polyethylene (PE) film by a simultaneous‐irradiation method. The influences of the grafting conditions were analyzed kinetically. The dependencies of the grafting rate on the dose rates and monomer concentrations ranging from 10 to 75 were found to be of 1 and 0 order, respectively. The overall activation energy for the graft polymerization was 2.05 × 104J/mol. The grafting rate was found to be independent of the film thicknesses ranging from 25 to
