Abstract
The invention relates to specific quaternized hyperbranched polymers having end-groups of formula (I) characterized in that said quaternized hyperbranched polymer is obtainable by preparation of a hyperbranched polymer having dimethylamino end groups by condensation of 2-dodecen-1-ylsuccinic anhydride, diisopropanolamine and N,N-bis[3-(dimethylamino)propyl]amine followed by quaternization of the dimethylamino end-groups to end groups of formula (I).
