The synthesis and characterization of a novel fixative, guar gum-graft-poly(acrylamide-co-diallyldimethylammonium chloride) (GG-g-p(AM-co-DADMAC)) polymer is described. The grafted polymer proved to be effective at absorbing hydrophobic wood resins from the water phase where they have a tendency to aggregate and form troublesome deposits. The new polymer combines 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-g-p(AM-co-DADMAC)was effective over the entire pH range as compared to other commercially available polymeric fixatives that were evaluated.
