| 摘要 |
The present invention relates to a particulate, linear, sheet-like or three-dimensional structure comprising, at least on its surface, a hydrophilicizing amount of at least one acylated polyamine, where at least some of the polyamine nitrogen atoms bear acyl radicals of the formula I <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>1</SUP>-CO- (I)<?in-line-formulae description="In-line Formulae" end="tail"?> where R<SUP>1 </SUP>is hydrogen, C<SUB>1</SUB>-C<SUB>27</SUB>-alkyl, C<SUB>7</SUB>-C<SUB>27</SUB>-alkenyl or C<SUB>6</SUB>-C<SUB>10</SUB>-aryl, and where the alkyl, alkenyl and aryl groups may bear at least one substituent selected from the class consisting of hydroxyl, alkoxy, alkoxycarbonyl and NE<SUP>1</SUP>E<SUP>2</SUP>, where E<SUP>1 </SUP>and E<SUP>2 </SUP>may be identical or different and are hydrogen, alkyl or acyl, to the use of acylated polyamines for modifying the surface properties of solids, and also to a process for modifying the surface properties of particulate, linear, sheet-like, or three-dimensional structures. |
