- 30 - METHOD FOR PREPARING SILICONE-TREATED STARCH ABSTRACT A method for treating starch with organosiloxane polymers is described in which the organosiloxane polymer is contacted with starch in an aqueous dispersion at a temperature of from 60°C to 98°C for a period of at least 60 seconds. Starch treated by this method can be useful as glue, a binder, a filler, or a coating. Starch treated with aminoalkyl- or epoxyalkyl- substituted polydimethyl- siloxane is especially useful as a water repellent sizing for substrates such as paper and textiles.
