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 1):
A method of making a cellulosic product comprising:\n i. introducing into a papermaking process a composition comprising a non-ionic surfactant R 1 \u2014O-A-O\u2014R 2 , wherein\n the residue \u2014O-A-O\u2014 is derived from a polyalkylene glycol HO-A-OH that comprises monomer units derived from an (C 2 -C 6 )-alkylene glycol or a mixture of at least two different (C 2 -C 6 )-alkylene glycols; and \n R 1  is selected from the group consisting of \u2014H, \u2014(C 8 -C 20 )-alkyl, \u2014(C 8 -C 20 )-alkenyl, \u2014(C\u2550O)\u2014(C 8 -C 20 )-alkyl and \u2014(C\u2550O)\u2014(C 8 -C 20 )-alkenyl, and \n R 2  is selected from the group consisting of \u2014H, \u2014(C 1 -C 6 )-alkyl, -benzyl, \u2014(C\u2550O)\u2014(C 8 -C 20 )-alkyl and \u2014(C\u2550O)\u2014(C 8 -C 20 )-alkenyl; and \n ii. a water-soluble or water swellable ionic polymer, wherein the water-soluble or water swellable ionic polymer is derived from a monomer composition containing a) one or more non-ionic ethylenically unsaturated monomers, and/or b) one or more cationic ethylenically unsaturated monomers, and/or c) one or more anionic ethylenically unsaturated monomers; and wherein the water-soluble ionic polymer is derived from a monomer composition containing not more than 50 ppm cross-linking monomers, relative to the total content of monomers in the monomer composition; and producing the cellulosic product.
