Abstract
A process for the production of a cold-water dispersible, starch half ester of a hydrocarboxyl-substituted succinic or glutaric acid, particularly the starch half ester of n-octenylsuccinic acid, includes the step of gelatinising and partially degrading the granular starch half ester, preformed in a manner known per se, by heating the half ester under shearing conditions, e.g. in an extruder, in the presence of water. Milling of the product gives a fine powder which is more readily dispersible in water to give a lump-free dispersion than is the alternative roll-dried ester.
