Abstract
Particles having an average diameter of at least 30 nanometers include a polymerization product of a silanol, a cyclic silazane, and an isocyanate. The particles are formed in an oil-in-water emulsion which includes less than 0.1 weight percent of a hydrophobic costabilizer. The particles are formed by a method including the step of reacting the silanol and the cyclic silazane and the isocyanate and the step of forming the oil-in-water emulsion.
