Preirradiation Graft Polymerization of Styrene in a Poly(tetrafluoroethylene) Film Investigated by Time-Resolved Small-Angle Neutron Scattering

Figure 1

(a) A preparation procedure of polymer electrolyte membranes based on poly(tetrafluoroethylene), which is composed of three steps of (1) crosslinking, (2) grafting by Preirradiation and (3) sulfonation. (b) A schematic view of Preirradiation graft polymerization with a crystalline domain and its interface. Long living radical is accumulated in a crystalline domain, whereas monomers access from an amorphous domain.
