Because inorganic/polymer nuclear shell material its concurrently inorganic and polymer merit, prepares is paid attention. These performance fine nuclear shell material oneself in the light, the electricity, magnetism, the machinery as well as the catalyzed aspect has demonstrated the widespread application prospect. Prepares the inorganic/polymer nuclear shell material the method to be very many, in which emulsion polymerization is one kind of easiest most and feasible preparation nanometer level only disperses the inorganic/polymer particle the method. In this article in second, three chapters, the main research take the silicon dioxide granule as the nucleus, gathers to the styrene sulfonic acid sodium/gathers for the shell silicon dioxide to the styrene sulfonic acid sodium nuclear shell compound microballoons synthesis, and discussed the catalyst, the different solvent to silicon dioxide microballoons factors and so on particle size and appearance influence as well as initiator, monomer, silicon dioxide granule and response medium allocated proportion/gathers to the silicon dioxide to the styrene sulfonic acid sodium nuclear shell compound microballoons using examination methods and so on the FTIR and SEM has carried on the attribute and the research to a nanometer granule and the polymer.
