FIELD: process engineering.
SUBSTANCE: invention relates to filtration membranes, particularly, to production of tubular elements for ultra- and micro-filtration. Proposed method comprises dissolving polysulphone (PSU) in methyl pyrrolidone, mixing it with hydropyle and porophore additive, applying obtained solution on inner surface of open pore tube and curing polysulphone. Mix of laprol and polyethylene glycol is used as said hydropyle and porophore additive.
EFFECT: stable viscous process solutions, better filtration.
