Abstract:
The current method relates to the use of a composition comprising a non-ionic surfactant and an ionic polymer in papermaking processes. The compositions are useful inter alia as retention aids and/or drainage aids when added to cellulosic suspensions.

Claim (Index 8):
The method according to  claim 1 , wherein the non-ionic ethylenically unsaturated monomer is selected from the group consisting of\n (a1) a non-ionic monomer of general formula (I) wherein R 3  represents hydrogen or C 1 -C 3 -alkyl, and R 4  and R 5  each independently represent hydrogen, C 1 -C 8 -alkyl or C 1 -C 5 -hydroxyalkyl; and (a2) a non-ionic amphiphilic monomer of formula (II) wherein Z 1  represents O, NH or NR 9  with R 9  being C 1 -C 3 -alkyl, R 6  represents hydrogen or C 1 -C 3 -alkyl, R 7  represents C 2 -C 6 -alkylene, R 8  represents hydrogen, C 8 -C 32 -alkyl, C 8 -C 32 -aryl and/or C 8 -C 32 -aralkyl, and n represents an integer between 1 and 50; the cationic ethylenically unsaturated monomer is a monomer of formula (III) wherein R 10  is hydrogen or C 1 -C 3 -alkyl; Z 2  is O, NH or NR 11  with R 11  being C 1 -C 3 -alkyl; and Y 0  is C 2 -C 6 -alkylene, substituted with one or more hydroxy groups, Y 1 , Y 2 , Y 3 , independently of each other, are C 1 -C 6 -alkyl, and X \u2212  is a halogen, pseudo-halogen, acetate or SO 4 CH 3 \u2212 ; and the anionic ethylenically unsaturated monomer is selected from the group consisting of (c1) ethylenically unsaturated carboxylic acids, carboxylic anhydrides, and water-soluble alkali metal salts, alkaline earth metal salts, and ammonium salts thereof, (c2) ethylenically unsaturated sulfonic acids and water-soluble alkali metal salts, alkaline earth metal salts, and ammonium salts thereof, (c3) ethylenically unsaturated phosphonic acids and water-soluble alkali metal salts, alkaline earth metal salts, and ammonium salts thereof, and (c4) sulfomethylated and/or phosphonomethylated acrylamides and water-soluble alkali metal salts, alkaline earth metal salts, and ammonium salts thereof.
