摘要：
The fluoropolymer poly(vinylidene fluoride) was irradiated with gamma rays to induce a polystyrene (PS) radiation grafting via an indirect method. Electron spin resonance and Fourier transform infrared studies were performed to identify the species that initiated the PS grafting. Specific experiments were performed to prove separately the importance of each kind of radical. A localization of the radicals in this irradiated polymer is proposed, and a kinetic model of the grafting is given. (C) 2001 John Wiley & Sons, Inc.
