ABSTRACT:
A process of preparing spherical nano-sized core/shell silica particles, including providing a latex polymer dispersion comprising particles of a liquid dispersible starting polymer in a dispersion liquid, adding at least one functionalized monomer to the latex polymer dispersion and polymerizing the at least one functionalized monomer on the particles, and growing an outer silicate shell on the particles through addition and reaction of at least one silane monomer.
