Abstract:
A process for the inhibition of misting in water-based cooling lubricants comprising adding a copolymer consisting of 20 to 35% by weight of structural units derived from a compound of formula 1 and 65 to 80% by weight of structural units derived from a compound of formula 2 ##STR10##in whichR.sup.1 and R.sup.2 independently of one another are a terminally unsaturated alkenyl radical having 3 to 5 carbon atoms,R.sup.3 and R.sup.4 independently of one another are C.sub.1 -C.sub.4 alkyl,R.sup.5 is H or C.sub.1 -C.sub.4 alkyl,R.sup.6 is a branched or unbranched C.sub.1 -C.sub.6 alkylene radical,X is an anion, andY is an alkali metal,to a water-based cooling lubricant, wherein the copolymer is added in an amount of from 0.01 to 2% by weight.
