ABSTRACT:
A process for dry cationization of starch or a starch-containing material comprises reacting the starch or starch-containing material with a dialkyl(epoxyalkyl)amine or trialkyl(epoxyalkyl) ammonium halide in a medium containing a maximum of 40% by weight of water in the presence of an alkali metal or alkaline earth metal oxide or hydroxide and a finely-divided aluminosilicate clay, having a cation-exchange capacity less than about 15 meq/100 g.
