ABSTRACT:
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 consisting of an electrical conductor, and an insulating layer provided on its surface. The insulating layer is obtained by heating a second polymer, in which main chains expressed in a chemical formula--[Si(R.sub.1).sub.2 --N(R.sub.2)].sub.n --are cross-linked with each other by chloroborazine through side chains containing trialkylsilyl radicals at a temperature of at least about 300.degree. C. and not more than 500.degree. C.
