ABSTRACT:
Organosilicon compounds containing β-ketoamide groups and organic polymer groups bound via enamine bonds are prepared by reaction of compounds bearing at least one β-ketocarbonyl functionality with organosilicon compounds bearing aminoalkylaminoalkyl groups. The products have the same uses as siloxanes containing polyether and acetoacetate groups.
