(57) Abstract: An inorganic filler coated with a silane coupling agent, which is excellent in workability and surface coating effect, and when added to a composition, reinforces the composition significantly, and contains the filler. To provide an organic polymer composition having excellent strength. An inorganic filler coated with a silane coupling agent, which is surface-treated with a coating agent containing a silane coupling agent and a film-forming resin, and an organic polymer composition containing the filler and an organic polymer. |
