FORFARANDE OCH PREPARAT FOR ATT MOTVERKA AVSETTNING AV HARTS OCH PIGMENT I CELLULOSAFIBERUPPSLAMNINGAR

摘要

A neutralized solution of polymer prepared by the free radical polymerization of an alpha, beta unsaturated acid, e.g., acrylic acid with small amounts of an alkyl ester an alpha, beta unsaturated acid and allyl alcohol when added to an aqueous pulp slurry at a rate of less than one percent polymer solids by weight of pulp present yields improved pitch and pigment dispersion and deposit control.
