Abstract (en)
Copolymers with units derived from acrylamide (I) and alkali metal acrylamido alkylsulfonate (II) are used in amounts of 0.01-2 wt.% to prevent mist formation in water-based cooling lubricants. Copolymers with units derived from acrylamide (I) and alkali metal alkali metal acrylamido alkylsulfonate (II) of the given formulae are used in amounts of 0.01-2 wt.% to prevent mist formation in water-based cooling lubricants; R<1> = hydrogen (H) or 1-4 carbon (C) alkyl; R<2> = branched or linear 1-6 C alkylene; Y = an alkali metal . An Independent claim is also included for water-based cooling lubricants containing 0.01-2 wt.% of this copolymer in addition to the usual base materials and optionally functional additives.
Abstract (de)
Gegenstand der Erfindung ist die Verwendung von Copolymeren, welche Struktureinheiten enthalten, die sich aus den Verbindungen der Formeln 1 und 2 ableiten <IMAGE> worin R<1>: H oder C1-C4-Alkyl; R<2>: einen verzweigten oder unverzweigten C1-C6-Alkylenrest; Y: ein Alkalimetall oder Ammonium bedeuten, zur Verhinderung der Nebelbildung in wasserbasierenden Kühlschmierstoffen.
