Abstract：

In order to develop an environmentally friendly and highperformance water treatment ultrafiltration membrane materials, the amphiphilic copolymers, poly (methyl methacrylate-co-butyl acrylate-co-methacrylic acid) (P(MMA-co-BA-co-MAA), PMBM), only containing only C, H and O elements were designed and synthesized in this research. The ultrafiltration membranes of PMBMs were prepared via typical non-solvent-induced phase separation (NIPS) process. It is found that suspension polymerization is an effective method to synthesize PMBMs, and the PMBMs can be prepared into ultrafiltration membrane with good pore structure. The carboxyl group in PMBMs can endow the membranes with good hydrophilicity and antifouling property. The performance of PMBM membrane with different carboxyl group content can vary obviously at different pH condition. The membrane of PMBM11 containing 11% (mass fraction) MAA performed a pure water flux of 1 310 L/(m2·h·MPa), a BSA retention rate of 98%, and a flux recovery rate (FRR) of 79% after BSA contamination.
