Abstract:

A method for the production of a hydrolytically stable nylon membrane includes providing a nylon having at least about 0. 9 moles of amino end groups per mole of nylon and preparing the nylon membrane therefrom. The membrane can be used in cartridges for use in filtration applications as may be necessary in the food and beverage industry as well as for the production of pharmaceuticals and the manufacture of electronic components. The membrane is capable of withstanding autoclaving and hot water sanitization without molecular dissociation regardless of its pore size, or thickness of the membrane, or the nylon solids content of the dope or, the temperature at which the dope is made.
