Abstract
Low molecular weight siloxane fluids are thickened by silicone elastomers. The silicone elastomers are made by combining in one pot an .tbd.Si--H containing siloxane, a mono-alkenyl polyether, an alpha, omega-diene, and a low molecular weight siloxane fluid. An elastomer, i.e. gel, with polyether groups is produced. The elastomer can be swollen with the low molecular weight siloxane fluid under shear force, to provide a uniform silicone paste. The silicone paste has excellent spreadability upon rubbing, and possesses unique rheological properties in being thixotropic and shear thinning. The silicone paste can be easily emulsified with water to form a stable uniform emulsion, without using a surfactant to allow normally immiscible materials to become intimately mixed.
