摘　　要：以聚偏氟乙烯 (PVDF)和聚醋酸乙烯酯 (PVAc)共混 ,采用相转化法制备亲水性小截留分子量共混超滤膜 .本工作的第一阶段 ,用稀溶液粘度法研究PVDF和PVAc的混溶性 。The hydrophilic small molecular weight cut-off(MWCO) blend ultrafiltration (UF) membranes are prepared from polyvinylidene fluoride(OVDF) and polyvinyl acetate(PVAc) by phase inversion method. The compatibility of PVDF and PVAc is researched by dilute solution viscosity method in the first step of the work. Results show that PVDF is compatible with PVAc at any rates.
