Publication number: 20160130397Abstract: The invention relates to a process for continuously preparing polyamide oligomers. This comprises continuous conveying of an aqueous solution of polyamide-forming monomers from a reservoir vessel into an oligomerization reactor, heating of the aqueous solution beyond a dissolution or storage temperature, the residence time of the monomer solution in the oligomerization reactor being limited and the pressure or the partial vapor pressure of the water being adjusted such that a conversion of monomers to polyamide oligomers does not exceed a maximum value and/or the polyamide oligomers formed do not phase-separate or spontaneously crystallize in solid form, and continuous discharge of the polyamide oligomers from the oligomerization reactor. A polyamide oligomer preparable by this process can be provided continuously in a mixture with water in a process for preparing a semicrystalline or amorphous, thermoplastically processible polyamide and then postcondensed to give a polyamide.Type: ApplicationFiled: June 11, 2014Publication date: May 12, 2016Inventors: Joachim Clauss, Stefan Schwiegk, Gad Kory, Christian Schmidt, Axel Wilms, Florian Richter, Ning Zhu, Sike Biedasek, Isa Alexandra Queiroz Da Fonseca, Heinrich Sack, Arnold Schneller, Achim Stammer, Volker Rauschenberger

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
