    • The present invention provides a surface modifier for an inorganic solid, of which a small amount improves efficiently and significantly the affinity of the inorganic solid with a medium, thus obtaining a composition having no bad effects even if the inorganic solid is blended in a large amount. That is, the present invention provides a surface modifier for an inorganic solid, which comprises a polyether having a monomeric unit represented by the formula (I); a inorganic solid having at least a part of its surface coated with the surface modifier; and a composition comprising the surface modifier and a inorganic solid: wherein R1 represents a hydrogen atom, a C1-50 hydrocarbon or fluoroalkyl group, a C6-50 fluoroaryl group, a Si1-50 siloxysilylpropyl group, etc.
    • 本发明提供了一种无机固体的表面改性剂,其中少量有效地提高了无机固体与介质的亲和性,从而获得即使无机固体大量共混也没有不良影响的组合物 。 也就是说,本发明提供了一种无机固体的表面改性剂,其包含具有由式(I)表示的单体单元的聚醚; 无机固体,其表面的至少一部分涂覆有表面改性剂; 以及包含表面改性剂和无机固体的组合物:其中R 1表示氢原子,C 1〜50烃基或氟代烷基,C 6 -50 氟代芳基,Si 1〜50族硅氧甲硅烷基丙基等
