Document Type and Number:
WIPO Patent Application WO2000029101
Kind Code:
B1
Abstract:
The invention relates to a flat or capillary or tubular microporous membrane, comprising a water-insoluble biocidal compound. This compound is preferably an N-halamine polymer, while most preferably it is poly-1,3-dichloro(dibromo, di-iodo)-5-methyl-5-(4'-vinylphenyl)- hydantoin. For water sterilization purposes the microporous membrane according to the invention comprises 0.5-12% by weight of poly-1,3-dichloro(dibromo)-5-methyl-5-(4'-vinylphenyl)hydantoin, and for air disinfection purposes 12-25% by weight. For disinfecting wound dressing the membrane according to the invention comprises 0.5-12% by weight of poly-1,3-di-iodo-5-methyl-5-(4'-vinylphenyl)hydantoin. Finally, the invention relates to a method for the manufacture of such a microporous membrane having an efficient antibacterial and -viral activity.
