Crosslinkable polymer composition, crosslinked polymer material, insulated electric wire, and wiring harness

Abstract

Provided are a crosslinkable polymer composition capable of forming a crosslinked structure by heating and capable of allowing a transition into a state having high heat-moldability from a state having low moldability at a certain temperature, a crosslinked polymer material obtained by crosslinking of the crosslinkable polymer composition, and an insulated electric wire and a wiring harness provided with the crosslinked polymer material. A crosslinkable polymer composition includes: ingredient A from which a metal ion is released upon heating; ingredient B composed of an organic polymer having a side chain including an electron-withdrawing substituent group capable of forming an ionic bond with the metal ion released from ingredient A; and ingredient C composed of a compound having a structure represented by formula (1) below and having a melting point of 190° C. or higher. The metal ion released from ingredient A crosslinks ingredient B to form a crosslinked product having a flow starting temperature of 190° C. or higher: where R represents a hydrogen atom or a hydroxyl group; m+n is 11 or more and 30 or less; and My+ represents a y-valent metal ion.
