A method for producing a polymer nanocomposite, includes: after expanding an interlayer space of a layered inorganic compound using an organic onium salt, immobilizing a radical polymerization initiator having a group represented by formula (1) on an interlayer surface of the layered inorganic compound via a covalent bond; and carrying out surface-initiated radical polymerization in a monomer from the immobilized radical polymerization initiator. Preferably, in the radical polymerization initiator having the group represented by the general formula (1), at least one of X1 to X3 in the formula is a chlorine atom, or R1 in the formula is a C1-25 alkylene group or a C2-25 alkenylene group optionally interrupted by an oxygen atom or an ester group and optionally substituted by a phenyl group:;
R1 represents a C1-25 alkylene group, a C2-25 alkenylene group, a C5-8 cycloalkylene group, or a C6-12 arylene group. |

1. A method for producing a polymer nanocomposite, comprising:
after expanding an interlayer space of a layered inorganic compound using an organic onium salt, immobilizing a radical polymerization initiator having a group represented by general formula (1) shown below on an interlayer surface of the layered inorganic compound via a covalent bond; and carrying out surface-initiated radical polymerization in a monomer from the immobilized radical polymerization initiator:wherein, R1 represents a C1-25 alkylene group, a C2-25 alkenylene group, a C5-8 cycloalkylene group, or a C6-12 arylene group, each of which being optionally substituted by a C1-18 alkyl group, a phenyl group, or a cyano group and being optionally interrupted by an oxygen atom, a carbonyl group, an ester group, a phenylene group, an amide group, or an imino group, the substitution and the interruption being optionally combined with each other; and X1 to X3 each independently represent a halogen atom, a hydroxy group, a methyl group, an ethyl group, a methyloxy group, or an ethyloxy group.
