‚ÄčAbstract:  Polyvinylidene fluoride ( PVDF) is one of the most used polymeric material for membranes thanks to its excellent properties as high mechanical strength, good chemical resistance and thermal stability as well as excellent aging resistance. Unfortunately, fouling is one of the major problem related to PVDF membranes for water treatment applications, since proteins and oils are absorbed by he hydrophobic PVDF and block the membrane pores. In order to overcome this drawback we propose to use linear and star amphiphilic PVDF-b-PEG copolymers (PVDF: hydrophobic, polyethylene glycol, PEG: hydrophilic) additives for PVDF membranes. In this presentation we will discuss the synthesis and molecular characterization of linear block copolymers.
