Es conocida la capacidad de los materiales inorg\u00e1nicos para mejorar las propiedades mec\u00e1nicas, t\u00e9rmicas, etc. De los pol\u00edmeros. Sin embargo, para mejorar las propiedades es imprescindible lograr la compatibilidad entre las fases org\u00e1nica e inorg\u00e1nica. Para lograr este objetivo, las dispersiones de poliuretano se han hecho reaccionar con un agente de acoplamiento (aptes). Para caracterizar las dispersiones se han utilizado, fundamentalmente, rmn, ftir y la dispersi\u00f3n de luz. Se ha hecho un trabajo sistem\u00e1tico para obtener dispersiones estables, sobre todo para encontrar las condiciones m\u00e1s adecuadas para la adici\u00f3n de la parte inorg\u00e1nica. debido a que las aplicaciones m\u00e1s importantes de estas dispersiones est\u00e1n en el campo de los recubrimientos y adhesivos, se han medido las propiedades m\u00e1s caracter\u00edsticas en estos \u00e1mbitos. As\u00ed, se ha determinado la influencia del aptes y la s\u00edlice en diferentes propiedades (t\u00e9rmicas y mec\u00e1nicas, fuerza de adhesi\u00f3n y permeabilidad al ox\u00edgeno). El comportamiento observado en muchas de estas dispersiones indican la posibilidad de que pueden ser candidatas interesantes para su desarrollo comercial.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos
