A novel graft copolymer was synthesized via graft copolymerization of an inimer, 2-(2- bromoisobutyryloxy) ethyl acrylate (BIEA), with ozone-pretreated poly (vinylidene fluoride)(PVDF)(the PVDF-g-PBIEA copolymer). Porous membranes could be fabricated from the copolymer solution by phase inversion. The BIEA polymer (PBIEA) side chains allowed the initiation of atom transfer radical polymerization (ATRP) of functional ...
