Patent number: 8999211Abstract: A process for producing porous structures from polyamide by dissolving the polyamide in an ionic liquid and precipitating or coagulating the dissolved polyamide by contacting the solution with a liquid precipitant medium. Fibers are produced from the dissolved polyamide in a wet-spinning process by precipitation in protic solvents, in particular water, a C1-4-alkanol or mixtures thereof, and subsequent freeze-drying. Foils, films or coatings are produced by blade coating the dissolved polyamide onto a substrate surface, optionally spraying with protic solvent, in particular water, a C1-4-alcohol or mixtures thereof, dipping into a precipitation or coagulation bath, freeze-drying of the resulting foil, of the film or of the coated substrate. Molded parts are prepared by extracting the dissolved polyamide with protic solvents, preferably water, a C1-4-alcohol or mixtures thereof, wherein the dissolved polymer is transformed to a solid or wax-like state by cooling and extracted after subsequent molding.Type: GrantFiled: February 11, 2009Date of Patent: April 7, 2015Assignee: BASF SEInventors: Stefan Schwiegk, Axel Wilms, Ronald Frans Maria Lange, Michael Siemer, Giovanni D'Andola, Volker Rauschenberger, Frank Hermanutz, Frank Gaehr, Julien Courtois, Dirk Gerhard
