Excellences of the living radical polymerization are suppressing termination by radicals transfer and avoiding the side reactions during the process. And maintaining a relatively narrow molecular weight distribution. In this studying, catalyst system is CuCl and DMDP, which transfers fluorine atom and produces radicals to synthesis graft copolymer of PVDF and PMMA. Make membrane by different percentage mixing graft copolymers and PMMA in solution blending. Membrane structures become porous after etching PMMA by solvent. Preparation of nano-porous membranes under different conditions. Graft copolymer and PMMA display miscible under mixing proportion is 65/35 of PVDF and PMMA. Porous membranes have homogeneously pore diameter in the range of 15∼20 nm. And dielectric constant value is also the decline by a wide range.
