Hydrophobically modified cationic polymer

摘要

The present invention relates to hydrophobically modified cationic polymers obtainable by the polymerization of one or more cationic ethylenically unsaturated monomers with an ethylenically unsaturated monomer having anhydride, imide, lactone, carboxylic acid, isocyanate or blocked isocyanate group and a reactive siloxane and processes for preparing them. These polymers are useful i.a. as a depositioning aid of hydrophobic actives onto fibrous substrates.

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).
