Abstract: Compositions are disclosed containing a polymeric mixture diluted into an aqueous solution, which can be usefully applied to any surface mat is hydbcphoixc to act, for example, as an aotifoggiag coating with minimal optical distortion and excellent transparency. The compositions can also be used as lubricious agents on medical implants, shunts, and surgical supplies to minimize tissue trauma, to maximize bio-compatibility, and to increase healing by enhancing better irrigation and flow in adjacent tissue.

Abstract: Soy protein and carbohydrate containing binder compositions are described. The binder compositions may include a carbohydrate, a nitrogen-containing compound, and a soy protein. The binder compositions may also optionally include thickening agents such as modified celluloses and polysaccharides.

Abstract: The present invention provides an improved method of producing a stable acid denatured soy/urea adhesive having improved wet and dry strengths, with more efficient production and lower production costs. The method comprises combining urea with soy flour that has been acid treated until denatured and substantially free from urease activity. The soy flour is preferably lowered to a pH of 2.0 to 4.0 for at least 1 minute. Optionally, the method may also include adding a crosslinking agent, diluent or both to the soy flour/urea adhesive and/or adding an emulsified or dispersed polymer. Adhesives and dispersions prepared according to the methods of this invention offer increased stability and strength properties.

Abstract: Biocompatible phase invertible proteinaceous compositions and methods for making and using the same are provided. Phase invertible compositions in accordance with the invention are prepared by combining a liquid proteinaceous substrate and a liquid crosslinking composition, where the liquid crosslinking composition includes a macromolecular crosslinking agent. Also provided are kits for use in preparing the subject compositions. The subject compositions, kits and systems find use in a variety of different applications.

Abstract: CMC with CMDS greater than or equal to 0.76, optionally with a non-ionic co-thickener or a CMC with CMDS less than 0.75 is used as both the rheology modifier and partial clay substitute in tape joint compounds. This significant reduction of clay level is sufficient to eliminate most of the negative characteristics of clay in joint compound.

Abstract: A filler comprising cellulose or lignocellulose fibrils on which light-scattering material particles have been deposited, and a process for the manufacture thereof. In the filler according to the invention, an alkyl derivative of cellulose, such as CMC, has been sorbed to the fibrils. Such a filler can be prepared from a source material containing cellulose or lignocellulose fibrils by first forming a fibril suspension, into which there are fed source materials forming an inorganic or organic salt that, when precipitating, forms a light-scattering pigment. The filler according to the invention has very good strength properties; in particular, good bond strength is achieved by means of it. The concentration of mineral pigment in paper can be increased and, furthermore, the grammage of paper can be lowered without the other important properties of the paper deteriorating.

Abstract: A mixture composition of a cellulose ether made from raw cotton linters and at least one additive is used in a ready mixed joint compound composition wherein the amount of the cellulose ether in the joint compound composition is significantly reduced. When this joint compound composition is mixed with water and applied to a substrate, the water retention, sag resistance, and workability of the wet joint compound are comparable or improved as compared to when using conventional similar cellulose ethers.

Abstract: Disclosed is a hybrid protein-polysaccharide superabsorbent hydrogel. The hydrogel includes two interpenetrating matrices: a first matrix which is an acylated, cross-linked protein matrix, and a second matrix which is an anionic polysaccharidc matrix. The two matrices can be non-cross-linked, or the hydrogel can further include bridging moieties that covalently cross-linking the acylated, cross-linked protein matrix to the anionic polysaccharide matrix.

Abstract: Powder mixtures and a method of forming and shaping the mixtures. The method involves compounding the components of powder materials, binder, solvent for the binder, surfactant, and non-solvent with respect to at least the binder, the solvent, and the powder materials. The non-solvent is lower in viscosity than the binder combined with the solvent. The solvent is present in an amount that is less than the amount that would be present otherwise. The components are mixed and plasticized, and shaped to form a green body. The choice of components results in improved wet green strength in the green body. The method is especially useful for extrusion processing of aqueous binder systems such as water and cellulose ethers and hydrophobic non-solvents, to form structures such as honeycombs. In the body, the ratio, upon subsequent firing, of the isostatic strength to the A-axis strength is at least about 20% higher than in bodies made without the mixture composition of the invention.
