Mechanistic study on radiation-induced graft polymerization into a fluorinated polymer film

Ko, B.-S.*; Hasegawa, Shin; Hamada, Takashi; Yoshimura, Kimio; Maekawa, Yasunari

The mechanism of radiation-induced graft polymerization (RGP) have been investigated through swelling-induced detachment phenomenon of graft-polymers from poly(ethylene-co-tetrafluoroethylene) films, prepared using various styrene/solvent mixture. This method newly provides various properties of graft polymers, such as number-average molecular weights (Mn), weight-average molecular weights (Mw), polymer distribution index (PDI: 1.9-2.5), and a number of graft polymers (${it N}$${it $rho$}$: 7.5 $$times$$ 10$$^{17}$$-1.4 $$times$$ 10$$^{18}$$ g$$^{-1}$$). These results reveal that the effect of monomer concentration is not significant on the RGP kinetics; however, the polarity of the solvents affects the RGP kinetics. Namely, poor solvents delayed initiation of polymerization and induced "gel-effect" significantly, resulting in faster kinetics of RGP.
