Described is a method of making a silicone in waternemulsion. The method comprises mixing (I) a compositionncontaining at least one polysiloxane, at least onenorganosilicon material that reacts with said polysiloxane byna chain extension reaction and a metal containing catalystnfor said chain extension reaction, (II) at least onensurfactant and (III) water to form a mixture. The mixture isnemulsified to form an emulsion which can have a wide varietynof silicone volume fractions, a broad range of mono-dispersenparticle sizes and a wide variety of molecular weightnpolymers. |
