The formation process and morphology of BTDA-TDI/MDI co-polyimide (P84, CAS#: 58698-66-1) asymmetric flat sheet membranes have been studied. Experimental results indicated that the weight ratio of H 2 O and N-methyl-2-pyrrolidone (NMP, CAS#: 872-50-4) at cloud point curve (above critical point) was
