McLean, D., Agarwal, V., Stack, K., Horne, J., and Richardson, D. (2011). "Synthesis of guar gum-graft-poly(acrylamide-co-diallyldimethylammonium chloride) and its application in the pulp and paper industry," BioRes. 6(4), 4168-4180.


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 polymerproved to be effective at adsorbing hydrophobic wood resin particles onto papermaking fibre surfaces, thus removing 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.
