Abstract: The adhesive compositions that include starch derivatives, plasticizers, optionally cellulose derivatives, and optionally other additives. By tailoring the composition and concentration of these components, hot melt adhesive compositions, hot melt pressure sensitive adhesive compositions, and pressure sensitive adhesives have been produced. Further, these adhesive compositions may be useful in articles including diapers, laminates, repositionable advertisements, and many more.

Abstract: Novel modified starch products and methods of preparation thereof are disclosed, wherein the starch products exhibit excellent water hydration and emulsion stabilization properties, while substantially maintaining individual granular structure. The modified starches are expanded or preswelled and cross-linked, preferably using a phosphate cross-linker, followed by substitution with hydrophobic moieties such as those derived from suitable acids or acid anhydrides.
