A selection of possible chemical reactions between FEP and styrene during direct and indirect irradiation. The high-energy electrons may interact with either FEP or styrene to produce an excited state species that will result in radical species. These radical species undergo propagation reactions that result in the polymerization of styrene, as shown in the desired polymerization of styrene on FEP and the undesired homopolymerization. There are also desired termination reactions such as the grafting of styrene, or the undesired FEP crosslinking.
