ABSTRACT:
Hollow fiber membranes can change dimensions upon drying or other processing creating leaks in tubesheets formed on fiber bundles. An adherent layer is formed in contact with an inner surface of each tubesheet and the fiber membranes therein in such a manner as to fill gaps formed between the hollow fiber membranes and each tubesheet during the drying or processing of the hollow fiber membranes and tubesheets. Preferably, the adherent layer is cast from a diglycidyl ether of bisphenol A containing an acrylo-nitrile-modified polyamine curing agent and the hollow fibers are cellulose ester.
