A novel fixative, guar gum-graft-poly(acrylamide-codiallyldimethylammonium chloride ) (aka GG-gp( AM-co-DADMAC)) was developed. This new grafted polymer proved to be very effective at adsorbing hydrophobic wood resin particles onto papermaking fibre surfaces and thus removing the troublesome wood resins from the water phase where they have a tendency to aggregate and form troublesome deposits. The new polymer is unique in that it takes advantage of the colloidal stabilising features of a natural product, guar gum and the wood resin fixative properties of a synthetic polymer p(AM-co-DADMAC)). GG-gp( AM-co-DADMAC was effective over the entire pH range as compared to other commercially available polymeric fixatives that were evaluated.
