The invention related to process for the production of paper from an
aqueous suspension containing cellulosic fibers, and optional fillers,
which comprises adding to the suspension (i) a cationic vinyl addition
polymer prepared by polymerizing one or more ethylenically unsaturated
monomers comprising a cationic monomer; (ii) an anionic polymer having
one or more aromatic groups selected from the group consisting of
polymers obtained by condensation of formaldehyde with benzene-based and
naphthalene-based compounds, polyurethanes, polysaccharides, and
lignin-based polymers; wherein (i) and (ii) are separately added to the
suspension; and (iii) a low molecular weight cationic organic polymer
having a molecular weight in the range of from 2,000 to about 700,000; or
an anionic microparticulate material; and forming and draining the
obtained suspension on a wire.
