Abstract
A novel method for making stable aqueous microemulsions of high molecular weight polydiorganosiloxanes which comprises sequentially adding at an effective rate a standard emulsion comprised of polydiorganosiloxane precursor, surfactant, and water to a polymerization catalyst medium while mixing to form a clear, stable aqueous microemulsion of polydiorganosiloxane.
