Abstract：

PLA-PEG-PLA block copolymers with different molecular weight (MW) were synthesized, and characterized by NMR . Then the copolymer was used as hydrophilic addition agent to prepare PLA hollow fiber membrane by blending method. Many properties of material were tested, such as water permeability,residual property, surface water contact angle, relative permeability, BSA rejection .Samples were also analysed by scanning electron microscope. The results showed that PLA-PEG-PLA with larger Mw lead to higher anti-fouling properties in accordance.
