Abstract
The present invention relates to second grade starches and wheat 'B' starches in particular which, following conventional modification treatments to produce a correspondingly viscosity-reduced starch, are especially useful in the production of Stein-Hall corrugating adhesives. Corrugated paper board products manufactured using such adhesives have improved properties. In one aspect of the present invention there is provided a modified wheat 'B' starch wherein aqueous dispersions of the modified 'B' starch have reduced viscosities relative to comparable dispersions of a corresponding unmodified wheat 'B' starch, the reduced viscosity not being less than about 12 centipoise grams per cubic centimeter for a specified dispersion.
