Summary: The grafting of styrene into commercially available fluoropolymer films by the pre‐irradiation method has been investigated. Poly(tetrafluoroethylene) (PTFE), poly(tetrafluoroethylene‐co‐hexafluoropropylene) (FEP), poly(tetrafluoroethylene‐co‐perfluoropropylvinyl ether) (PFA) and poly(tetrafluorethylene‐co‐ethylene) (ETFE) were chosen as the base polymer material. The influence of the base material, the pre‐irradiation dose, and the storage time between the irradiation and the grafting step on the yield of grafting was examined. The base materials were pre‐treated by irradiation in the molten state under oxygen‐free conditions in order to create branches and cross‐links. The effect of pre‐treatment on the yield of grafting was studied.
