PROBLEM TO BE SOLVED: To provide a polymer-grafted colloidal silica in which colloid crystals are regularly arranged as fine particles in an organic solvent, and a polymer-grafted colloidal silica dispersed body.;SOLUTION: The polymer-grafted colloidal silica is prepared by binding a silyl residue, that is prepared by hydrolyzing a polymeric silane coupling agent represented by general formula (1), to a colloidal silica, wherein, in the general formula (1), R1 is a methyl group or a hydrogen atom, R2 is a methoxy group [CH3O-], a methyl amino group [CH3NH-], a dimethyl amino group [(CH3)2N-] or an isopropyl amino group [(CH3)2CHNH-], R3 is a methyl group or a hydrogen atom, m is a positive number of 18-300, and n is a positive number of 3-100.;COPYRIGHT: (C)2008,JPO&INPIT
