ABSTRACT:
Crosslinked starch is reacted with an epihalohydrin in the presence of a strong acid catalyst to produce the 3-halo-2-hydroxypropyl ether. Substitution of the halogen with nitrogen-containing compounds enables the preparation of novel water-insoluble cationic, anionic, and chelating starch ethers, as well as starch ethers having degrees of substitution heretofore unattainable in the prior art.
