ABSTRACT:
A novel starch ether derivative of which the crosslinking properties may be altered by adjusting the pH of the cook is prepared by reacting under controlled conditions a starch base in aqueous medium with an N-(alkoxymethyl)acrylamide wherein the alkoxy group contains 1-4 carbon atoms, and is preferably an isobutoxy group. The starch derivatives herein may be used as insolubilizing or strengthening agents in adhesives, coatings, and in other applications wherein controlled crosslinking is desirable.
