Beschreibung
Zusammenfassung:	The present invention provides for a method for reducing the acrylamide present in water-in-oil emulsions of acrylamide polymers with Amidase which comprises adding the Amidase to the water-in-oil emulsion of the acrylamide polymer upon completion of its polymerization, characterized by subjecting the thus treated water-in-oil emulsion to one or more of the following steps: a) pH adjustment b) heating c) inert gas sparging d) adding a chemical reducing agent a
