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 18):
A method of improving retention of an aqueous cellulosic suspension comprising\n (i) subjecting an aqueous reaction mixture comprising at least one of a non-ionic ethylenically unsaturated monomer, a cationic ethylenically unsaturated monomer, or an anionic ethylenically unsaturated monomer, wherein the anionic or cationic ethylenically unsaturated monomer is derived from a monomer composition that contains not more than 50 ppm cross-linking monomers, relative to the total content of monomers in the monomer composition, optionally an ionic polymeric dispersant, and optionally a non-ionic surfactant, to radical polymerization by adiabatic gel polymerization, thereby obtaining a gel; (ii) optionally crushing or chopping the gel; (iii) drying the gel or the crushed or chopped gel at a temperature of from 70\u00b0 C. to 150\u00b0 C., thereby obtaining a dried material; (iv) optionally grinding the dried material; and (v) adding the non-ionic surfactant R 1 \u2014O-A-O\u2014R 2 ; wherein said adding (v) is performed before said subjecting (i), after said optionally grinding (iv) or at any time in between; and\n adding the composition to the cellulosic suspension.
