  • Publication number: 20180051417
    Abstract: A method of making paper comprising adding to an aqueous suspension of cellulosic pulp slurry a polymer in the form of an inverse emulsion comprising a cationic poly N,N-(dialkylaminoalkyl) (meth)acrylamide or it's quaternates or salts, and dewatering the cellulose pulp slurry to form a paper or paperboard product, wherein the pulp slurry contains more than about 75 weight ppm of water soluble lignin based upon total pulp slurry weight, and wherein the polymer is added to the pulp slurry at a dosage of 0.001 to 1% by weight based upon cellulose pulp solids, and wherein the polymer optionally contains multi-functional monomer.

  • Patent number: 8399544
    Abstract: The invention is directed to composition, preparation and use of composite materials based on an adhesive with solids levels above 45% by weight that contain stable polyamidoamine-epihalohydrin resins (PAE resins) of solids greater than 40% where the relative high solids of the PAE enables the high solids content of the adhesive. Furthermore, at least 45% of the solids portion of the adhesive is made up of a combination of the solids of the PAE resin and the solids of the protein source. The invention is also directed an adhesive comprised of the PAE in combination with a soy protein source. The invention is also directed toward use of the adhesive in composite materials and in particular wood containing composite materials, and more specifically wood fiber or particle based composites.

  • Publication number: 20100093896
    Abstract: The present invention discloses an adhesive composition comprising a protein component, an azetidinium functionalized polymer component and a viscosity modifying component. The preferred protein is a soy protein and the viscosity modifying component is preferably a sulfite reducing agent, a thiol, or combinations thereof. The invention provides for a high solids, lower viscosity adhesive formulation. The present invention also relates to a composite and a method of making a composite comprising a substrate and the adhesive composition of the present invention.
