This invention relates to a degraded, inhibited cationic starch for use in papermaking systems, which affords improved physical properties, particularly strength. Additionally these derivatives provide easy-to-prepare alternatives totraditional starches, and can even be added directly to the papermaking process without cooking. While the benefits of these starch compositions can be applied to any type of papermaking method, they are especially useful in high shear, high conductivity and recycle systems.

Starches for use in papermaking

This invention relates to a method of producing a bioadhesive composition comprising the steps of preparing a solution of a solvent and a polymer mixture wherein the polymer mixture comprises at least one natural or synthetic polycarboxylated polymer and at least one polysaccharide; drying the solution to form a solid; and heat treating the solid to effect cross-linking and to form the bioadhesive composition.

Bioadhesive composition

This invention is directed to degraded, hydrated particulate starches that are hydrophobically modified and a method of providing paper with reduced porosity, resistance to liquid penetration and increased surface strength comprising applying to the surface of a paper substrate an effective amount of a surface sizing composition which comprises such starch. In particular, the starches are those in which the starch base is degraded to a water fluidity (WF) of from about 10 to 80 or the modified and/or particulate starch is degraded using a substantially equivalent amount of degradation agent and substantially the same reaction conditions, the starch is modified with a hydrophobic hydrocarbon group of 5 to 23 carbon atoms at about 1 to 20% substitution level by weight of bound hydrophobe based on the weight of starch, and the hydrated starch has a volume average hydrated particle size of at least about 20 microns and a volume fraction of hydrated particles at 1% solids of at least about 5%.

Various novel acetal- and aldehyde-containing monomers are prepared. They can be polymerized and copolymerized by conventional polymerization techniques. The polymers contain repeating units derived from one or more ethylenically or allylically unsaturated monomers containing an acetal group or aldehyde group and optionally one or more repeating units derived from ethylenically or allylically unsaturated monomers other than the acetal-containing or aldehyde-containing monomer such as ethylene, vinyl acetate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, methyl methacrylate or acrylic acid. Aqueous emulsions of polymers containing the acetal-containing monomers and a hydroxy-containing monomer are useful as binders for nonwoven fabrics.
