Abstract
A method for improving the extrusion characteristics of finely divided aqueous starch-polymer mixtures comprising subjecting the admixture to deaeration and compaction to form a hard shaped form therefrom, milling the hard shaped form of starch and polymer admixture to form granules. Granules of selected size are then coated with a lubricating compound.
