Abstract
The invention relates to chemical industry, in particular to manufacturing articles from aliphatic polyamide, production of films of polyamide solutions. A process for the production of microcellular polymer filters involves polyamide solubilization in the mixture of formylic acid and water, forming solution on carrier, exposure of the air, coagulation, washing with water and drying. Ethyl alcohol is added to the mixture for polyamide solubilization.
