This invention is about process to disperse organic nano-particles into non-aqueous resin medium. The process includes the steps of a) prepare resin dispersion/emulsion in water where the resin containing unsaturation in the polymer chain; b) cure the resin dispersion by adding monomer and initiator or initiator; c) add the cured dispersion/emulsion during the synthesis steps of resin medium. The amount of organic nano-particle in resin medium can be 2 to 30% by weight. Esta invención se refiere a un proceso para dispersar nanopartículas orgánicas en un medio resinoso no acuoso. El proceso incluye los pasos de a) preparar una dispersión de resina/emulsión de agua donde la resina contiene insaturación en la cadena de polímero; b) curar la dispersión de resina agregando monómero e iniciador o iniciador; c) agregar la dispersión/emulsión curada durante los pasos de síntesis de medio de resina. La cantidad de nanopartículas orgánicas en medio resinoso puede ser de 2 a 30% en peso.
