STARCH COMPOSITIONS AND METHODS OF MAKING STARCH COMPOSITIONS

摘要

A starch composition is made by cooking a starch and combining the cooked starch with a polymer, the polymer containing anionic groups or potential anionic groups. Another starch composition is made by combining a starch with a polymer, the polymer containing anionic groups or potential anionic groups, and cooking the combined starch and polymer composition. A dry starch composition, suitable for forming an additive for a paper furnish, includes a starch and a polymer containing anionic groups or potential anionic groups. Methods of making the starch composition are also disclosed.
