A papermaking method and a composition which utilize, as a drainage aid, a water soluble hydrophobically associative polymer which is a copolymer prepared from monomers which include a hydrophobic ethylenically unsaturated monomer, and one or more of a nonionic ethylenically unsaturated monomer, a cationic ethylenically unsaturated monomer, and an anionic ethylenically unsaturated monomer.

On décrit un procédé de fabrication de papier et une composition qui renferme, en tant qu'adjuvant d'égouttage, un polymère associatif soluble dans l'eau modifié de manière hydrophobe qui est un copolymère préparé à partir de monomères comprenant un monomère hydrophobe non saturé par l'éthylène et au moins un monomère non ionique non saturé par l'éthylène, un monomère cationique non saturé par l'éthylène et un monomère anionique non saturé par l'éthylène.
