摘要：

Remarkable highly porous structures are formed by the coagulation of incompatible phase-forming polymer blend solutions. The effect of an added polymer on the porosity of the primary layer is studied. Investigations of the permeability of membranes prepared by different procedures revealed that only in flat membranes prepared on a solid support an elevated porosity of the primary coagulated layer could be observed. A mechanism of pore formation in this special case is suggested.
