Beschreibung
Zusammenfassung:	A novel group of surface active agents is revealed. These surface active agents are the condensation product of an aldehyde or ketone of from 9 to 20 carbon atoms with a polyoxyalkyleneamine which is an amine terminated block copolymer of oxyethylene and oxypropylene groups. The Schiff bases of the present invention are characterized by the general formula: In this general formula, R1 and R2 can either be hydrogen or an alkyl radical such that the sum of carbon atoms in the radical R1-C-R2 is from 9 to 20. R3 is a radical which may be an alkyl of from 1 to 4 carbon atoms. R3 is in the alternative the radical H2N[CH(CH3)CH2]-[OCH(CH3)CH2]y-or In these formulae, y has an average value of from 1 to 3 and and x has an average value of from 4 to 60 such that the amount of polyoxyethylene in the Schiff base is greater than or equal to 40 wt. %.
