MANUFACTURE OF POROUS BODY WITH ADJUSTABLE TOTAL PORE VOLUME, ADJUSTABLE PORE DIAMETER AND ADJUSTABLE PORE WALL

摘要

porous body, in particular in the form of hohlfasern membranes are produced by heating a polymer above the upper critical temperature (t c) in a mixture of these two, in the lu00f6setemperatur liquid miscible compounds a and b, and the mixture polymerverbindu. if a and b in the liquid state, a mischungslu00fccke inthe connection a, a solvent for the polymer and the compound b, which is preferably a nichtlu00f6semittel or a quellmittel for the polymer is, the phasentrennungstemperatur a solution consisting of the polymer and the compound a dangerous precedent. after solidification, the components a and / or b may be extracted. by using no toxic substances, such asedible oils as a link a and castor oil as a link b body, non-toxic and safe in the medical field and in the food industry, etc. can be used.
