Cationic membranes were prepared by direct radiation grafting of acrylic acid (AAc) and methacrylic acid (MAA) onto poly(tetrafluoroethy1eneperfluoropropylvinyl ether) (PFA) films, followed by alkaline treatment to confer ionic character in the graft copolymer. The addition of inhibitor such as Mohr
The method of preirradiation grafting of acrylic acid and methacrylic acid onto polyethylene films was studied. The trapped radicals and hydroperoxides or diperoxides appeared to be able to induce graft polymerization. Mohr's salt was added to depress homopolymerization. The influences of crystallin
Radiation-induced grafting of styrene onto poly(tetraยฏuoroethylene) (PTFE) ยฎlms was studied by a simultaneous irradiation technique. Grafting was carried out using g-radiation from a 60 Co source at dose rates of 1.32ยฑ15.0 kGy h ร1 at room temperature. The effects of type of diluent, dose rate, irra
PFA-g-polystyrene graft copolymers were prepared by simultaneous radiation-induced graft copolymerization of styrene onto poly(tetrafluoroethylene-co-perfluorovinyl ether) (PFA) films. The effects of grafting conditions such as monomer concentration, dose, and dose rate were investigated. Three solv
