Synthesis of amphiphilic comb-shape block copolymers PSt-b-P(A-mPEG) and Studies on the antifouling property of blend modified polyethersulfone ultrafiltration membranes;

An amphiphilic polymer,acryl amide(AM)/vinyl acetate(VAc)/butyl acrylate(BA)was synthesized with the effects of amount of AM as well as the ratio between VAc and BA on surface tension,stability against centrifugation,emulsifying power and foaming power of the product examined.
