Abstract
Process for the preparation of a gas permeable sheet, characterized in that it comprises forming a solution of a polymer containing polyamide, precipitating the polymer from the solution to form a gel containing residual solvent, and reducing the solvent content of the gel at a temperature lower than the vitrification temperature of said gel, by which means the polymer tends to aggregate in micellar colloids, producing pores in the gel.
