Microporous films from polyurethane-based thixotropic composites. Effect of the content of precipitant in the composite and in the precipitation mixture

It is shown how the presence of precipitant (water) in the precipitation mixture dimethylformamide-water and in the polyurethane composite affects the structure, hygienic, and physico-mechanical properties of microporous films prepared from the composite by phase inversion.
