Abstract

A starch derivate with high absorption of aqueous fluids consisting of a water insoluble alkalisalt of a in aqueous alkaline hydrolysis medium hydrolyzed starch-acrylonitrile-graft copolymerisate obtained through graft polymerizing acrylonitrile on granular starch. By using for the hydrolysis a hydrolysis medium containing water, a lower alcohol and a further with water and the alcohol mixable organic solvent, which is more hydrophobic than the alcohol, a non-dusting granulate with a particle size in the range between 0,1 and 1,5 mm can be isolated direct from the hydrolysis medium. The granulate has excellent handling properties to be used as absorption agent for water and aqueous media.
