FIELD: chemistry.
SUBSTANCE: method includes preparing a thermoplastic solution in an organic solvent, crystallising the solution, moulding workpieces from the crystallised solution at temperature below the melting point of the solvent and removing the crystallised solvent. Before moulding, granules of the crystallised solution are ground and the required fraction of the obtained powder is collected. Moulding is carried out by extrusion. The crystallised solvent is removed by vacuum-sublimation drying at temperature not higher than 42°C.
EFFECT: high output of articles made of porous polymer material.
