Building a bridge poly- (ethylene oxide) the method of manufacturing the membrane which is based

摘要

This invention building a bridge poly- (ethylene oxide) regards the new manufacturing method of the membrane which is based.As for this method,a) independently or mixing the polymer or copolymer of the above-mentioned ethylene oxide, with the water soluble polymer, under existing of the effective quantity of the optical initiator or the building a bridge medicine, the water, have organic solvent, or the water of all ratios and the solvent type melt which consists of the blend of the organic solvent,b1) this solvent type from only the organic solvent when it is constituted, until solvent type evaporates, drying the solution which is obtained, the membrane which the dry film profit, 10 - 100 weight % it processes under the condition for making that the water of the quantity is absorbed possible is obtained, vis-a-vis the weight of the polymer?,b2) or, this solvent type from the blend of the water or the water and the organic solvent when it is constituted, until solvent type evaporates, drying the solution which is obtained, 10 - 100 weight % obtain the membrane which includes the water of the quantity vis-a-vis the weight of the polymer,c) irradiate the membrane which is obtained, sufficient period in order to make building a bridge possible, making use of the ultraviolet ray of the wave length 200 - 400nmIt is constituted from the process which consists of.Use: Especially in pharmacy or make-up field the useful organism material
