Microporous films, 0.3—1 mm thick, have been prepared by coagulating with water the 20-percent PA-6 solutions in 40—70 percent sulfuric acid (obtained by diluting concentrated H2SO4 with water or formalin). The sorption and desorption capabilities of these films were 2,5 times higher than those of the initial polyamide.
