- -. , . -, (, ). . : -, , , , , . A method of regular porous structure formation in dense membranes of silane-siloxane block copolymers was developed. The operation consists in treating the membrane in a solvent which is a good swelling agent for poly(dimethylsiloxane). The influence of block copolymer composition, swelling agent and conditions of treatment (time, temperature) on a porous structure formation was studied. The porous membranes was tested for removal of ethanol from aqueous solutions by membrane distillation. Keywords: block copolymers, membranes, porosity, membrane distillation, poly(vinyltrimethylsilane), poly(dimethylsiloxane).
