Abstract:
1. A hydrophobically modified cationic polymer obtained by the polymerization of (A) one or more cationic ethylenically unsaturated monomers, wherein (A) is diallyl dimethyl ammonium chloride and/or quaternized vinylimidazole, (B) an ethylenically unsaturated monomer having an epoxy, anhydride, imide, lactone, carboxylic acid or isocyanate functionality, (C) optionally a water-soluble monomer, and (D) a reactive siloxane, wherein the polymerization comprises: i) free-radical polymerizing (A), (B) and optionally (C) to obtain a polymer, and ii) subsequently polymer-analogous reacting the epoxy, anhydride, imide, lactone, carboxylic acid or isocyanate functionality of the polymer with (D).
