Heat resistant insulated wire and method of preparing the same.

摘要

Disclosed herein are a heat resistant insulated wire which is not decomposed but maintains insulativity under a high temperature with excellent adhesion of a coating film, and a method of preparing the same. The heat resistant insulated wire includes a base material (1) consisting of an electrical conductor, and an insulating layer (2) provided on its surface. The insulating layer (2) is obtained by heating a second polymer, in which main chains expressed in a chemical formula - [Si(R1)2 - N(R2)]n - are cross-linked with each other by chloroborazine through side chains containing trialkylsilyl radicals at a temperature of at least about 300 DEG C and not more than 500 DEG C.
