Abstract
A modified starch, exhibits: a weight-average molecular weight ranging from 250 000 to 2 000 000 Da; a solubility, measured according to a test A, ranging from 50 to 85%. A process for the manufacture of the starch and a process to the use thereof in the manufacture of an aqueous binder are also described.
