Abstract
The further modification of acid modified flours and starches by reacting such acid modified flours, at a pH of less than about 3.0 with an alkylene oxide, preferably ethylene oxide, in order to scavenge residual acidity, raise the pH of the product and partially crosslink it. The thus created new crosslinked product is useful in gypsum wall board core binders and other applications.
