More levels of nano-SiO〓 lead to larger particle size. An increase in polymerization reaction temperature causes the decrease in coagulum and increase in viscosity and particle size, and the nano-SiO〓 has same effects at certain temperature. When the levels of hydrophilic monomer acrylic acid and hydroxylethyl methacrylate in core composite are increased, the particle size of emulsifier-free emulsion decreases, in spite of the presence of nano-SiO〓.
