摘要：
Spherical crosslinked organic particles exhibit a good dispersibility in thermoplastic resins, thermosetting resins, paints, coatings, cosmetics, rubbers, and toners and carriers employed in electrostatic development. Highly efficient methods for preparing these crosslinked organic particles are provided. Suspensions of crosslinked organic particles have excellent handling properties, and are highly blendable with other components. Highly efficient methods for preparing these suspensions are also provided. The spherical crosslinked organic particles have an average particle size of 0.1-500 &mgr;m, and can be prepared by emulsifying in water using an emulsifying agent, a fluid composition containing (A) an organic compound that has at least 2 aliphatically unsaturated bonds in each molecule, (B) a silicon-containing organic compound that has at least 2 silicon-bonded hydrogen atoms in each molecule, (C) an hydrosilylation reaction catalyst, crosslinking the fluid composition by carrying out an hydrosilylation reaction, and thereafter removing water.
