Title: Silylated perfluorinated ion-exchange microcomposite catalysts

Abstract: This invention concerns a silylated porous microcomposite comprising a perfluorinated ion-exchange polymer entrapped within and highly dispersed throughout a network of inorganic oxide wherein the network and optionally the polymer have been modified with a silylating agent. These silylated microcomposites can be used in heterogeneous catalyst compositions for various chemical processes, such as in esterifications and acylations.
