Abstract
This paper reports the results of an investigation of pyropolycarboranes, nondeformable thermally stable cross‐linked polymeric materials obtained by pyrolysis of carborane‐containing polymers. Carborane‐containing polyamides and polyesters were heated in air under pressure and analyzed by thermomechanical and thermogravimetric methods. Moreover, the friction properties of the filled materials have been investigated. The effect of hydrogen liberation on the friction of filled pyropolycarboranes at elevated temperatures was used in developing self‐lubricating materials with friction coefficients at 300–400°C.
