Method of making silicone in water emulsions

摘要

Described is a method of making a silicone in water emulsion. The method comprises mixing (I) a composition containing at least one polysiloxane, at least one organosilicon material that reacts with said polysiloxane by a chain extension reaction and a metal containing catalyst for said chain extension reaction, (II) at least one surfactant and (III) water to form a mixture. The mixture is emulsified to form an emulsion which can have a wide variety of silicone volume fractions, a broad range of mono-disperse particle sizes and a wide variety of molecular weight polymers.
