Abstract：
 The invention is a phenodiazine sulphone ketone hollow fiber ultrafiltration membrane and its preparing method, its character: adopting phenodiazine PPESK as film raw material P, N,N-dimethylacetamide (DMAc), N-methyl pyrrolidone (NMP), or their mixture as solvent S, and polyethylene glycol (PEG) or oxalic acid as additive A, where P/(P+S)=15%-25% (weight ratio, the same below), A/P=0-4/5, and S1/(S1+S2)=0-1. At the same time, it gives the preparing method. It has high flux property besides the performance of resisting high temperature, oxidization and solvent.
