Process for the production of coupling agent-treated inorganic particles and use thereof

摘要

A process for the production of coupling agent-treated inorganic particles, which process is excellent in surface-treatment uniformity and uses a coupling agent at high coefficient of utilization, the process comprising adding a solution of a coupling agent into an aqueous suspension of inorganic particles with stirring and, after the mixing with stirring, heat-drying the resultant suspension without dehydration by filtration and concentration, and a synthetic resin composition containing the above particles and having excellent properties.
