ABSTRACT:
A process for the acid-catalyzed synthesis of polysiloxane emulsions is discussed. The process comprises preheating an aqueous reaction mixture, optionally comprising polysiloxane emulsion seeds, and optionally containing a surfactant, to a temperature of up to about 110.degree. C. and adding to the aqueous reaction mixture, water, an acid catalyst surfactant, and a polysiloxane precursor to form a polysiloxane emulsion comprising essentially multi-modal, optionally multi-layered particles having desired multi-modal particle sizes in a range of from about 100 nm to about 2 microns.
