Microporous latex membranes, related articles and methods

摘要

Novel microporous latex membranes having advantageous properties are disclosed as are methods for making and using the microporous latex membranes. Disclosed processes for making such membranes include those processes comprising applying a latex suspension to a surface to result in a latex coated surface and subjecting the latex coated surface to a first temperature less than about -2° C., and subsequent thereto, heating the latex coated surface at a second temperature to result in a microporous latex membrane. Moreover, it is disclosed that certain properties of the microporous membranes may be manipulated through judicious selection of first and second temperatures.
