ABSTRACT:
Herein are disclosed adducts of amines and polycarboxylic acids, and methods of making such adducts. Such adducts can be used to remove cyanogen chloride. Also disclosed are methods of providing such adducts on supports to form filter media. Also disclosed are methods of combining such filter media with catalysts and/or with porous polymeric webs to form filter systems.
