Abstract
A method is described for making a silicone emulsion. According to the method, there is formed a mixture of water, a cyclic siloxane, optionally a nonionic surfactant, and a cationic surfactant. There is then added to the mixture a polymerization initiator which can be a silanolate or an organosilanolate. The mixture is heated and agitated, and the cyclic siloxane is allowed to polymerize until an emulsion is formed. The benefit of this emulsion polymerization method is that the rate of emulsion polymer formation is enhanced. Thus, the method provides for the production of emulsions in a new and more efficient manner. The silicone emulsion will produce an elastomeric product when water is removed under ambient conditions.
