METHOD OF FORMING PARTICLES FROM AN OIL-IN-WATER EMULSION

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...

Beschreibung
Zusammenfassung:	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. L'invention concerne des particules ayant un diamètre moyen d'au moins 30 nanomètres qui comprennent un produit de polymérisation d'un silanol, d'un silazane cyclique et d'un isocyanate. Les particules sont formées dans une émulsion d'huile dans l'eau qui comprend moins de 0,1 pour cent en poids d'un costabilisateur hydrophobe. Les particules sont formées par un procédé comprenant l'étape de réaction du silanol et du silazane cyclique et de l'isocyanate et l'étape de formation de l'émulsion d'huile dans l'eau.
