Abstract

Nanoparticles of poly(phenyl/methylsilsesquioxane) (PPMSQ) were prepared by emulsion polymerization of the co-hydrolysate that had been formed from a mixture of trichlorophenylsilane (TCP) and trichloromethylsilane (TCM) in aqueous solution. The average size of the resultant particles was controlled from 30 to 250 nm in diameter by changing the initial concentration of the co-hydrolysate and the amount of the emulsifier added. The PPMSQ formed from the hydrolysate of TCP/TCM had a high cross-linking density, being insoluble and stable in nature. The ¹H NMR spectrum of the co-hydrolysate revealed that both the primary hydrolysates of TCP and TCM are involved in the fast co-polycondensation to afford meta-stable water-soluble oligomers having many silanol groups. These oligomers are allowed to react with each other to form the nanoparticles with the aid of emulsifier.
