Abstract

"PROCESSO PARA PREPARAR UMA DISPERSãO AQUOSA DE UMA PLURALIDADE DE PARTìCULAS POROSAS, DISPERSãO AQUOSA DE UMA PLURALIDADE DE PARTìCULAS POROSAS, E, PLURALIDADE DE PARTìCULAS POROSAS". Um processo de formar, pela polimerização em uma dispersão aquosa em pressões em excesso de uma atmosfera, uma pluralidade de partículas porosas tendo pelo menos uma fase polimérica e pelo menos uma fase de enchimento de poro, em que a fase de enchimento de poro inclui um enchedor de poro e uma substância fugitiva é divulgado. A substituição da substância fugitiva com um gás de substituição é ainda divulgada. Partículas porosas tendo uma fase polimérica e poros contendo um enchedor de poro e, opcionalmente, uma fase gasosa também são divulgadas, como o são suas dispersões aquosas.
