Abstract
Official abstract text for this publication.
A process for the preparation of a dispersion of starch in an hydroxylic liquid, the process comprising introducing a feed starch and an hydroxylic liquid to an extruder, and applying shear forces in the extruder to the starch and the liquid under conditions sufficient to prepare a stable dispersion of starch particles in the hydroxylic liquid.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for the preparation of a dispersion of starch in a hydroxylic liquid, the process comprising: introducing a feed starch and aft hydroxylic liquid selected from water, an alcohol, and mixtures thereof, to an extruder, and applying shear forces in the extruder to the starch and the liquid in the substantial absence of a cross-linker under conditions sufficient to prepare a stable dispersion of starch particles in the hydroxylic liquid, with the proviso that the dispersion has a solids content of at least 15%. 2. The process of claim 1 wherein the dispersion is a very stable dispersion. 3. The process of claim 1 wherein the number average particle size of the starch particles in the dispersion is from about 0.02 to about 0.4 microns. 4. The process of claim 1 further comprising a step wherein at least part of the hydroxylic liquid of the dispersion is removed. 5. The process of claim 1 wherein the SME is at least about 400 J/g. 6. The process of claim 1 wherein the extruder is a co-rotating, self wiping twin screw extruder. 7. The process of claim 1 conducted in the substantial absence of a surfactant. 8. The process of claim 1 wherein the number average particle size of the starch particles in the dispersion is from about 0.05 to about 0.2 microns. 9. The process of claim 1 wherein the Brookfield viscosity of the dispersion, measured 7 days after the dispersion is produced, is not more than about 1,000 cps. 10. A starch dispersion prepared by the process of claim 1 . 11. A coating composition comprising the starch of claim 10 . 12. The composition of claim 11 wherein the coating composition is a paper coating composition.
