Abstract

The results of investigating highly thermostable polymer matrices with softening temperatures of 400–450°C are reported. Binders based on a tetranitrile of an aromatic tetracarboxylic acid and bis(o-cyanoamine) are used as polymer matrices. Traditional antioxidants, such as aromatic amines, phenols, and alkyl aryl phosphites, cannot be applied as thermostabilizers. Detailed tests of an efficient stabilizer carborane-containing dinitrile were also unsuccessful because the initial period of retardation in the thermal-oxidative degradation is followed by irreversible changes in the polymer at 350–400°C. Only a new thermostabilizing system based on carborane-containing aromatic compounds with a set of conjugated bonds demonstrates a positive effect. It is established that the developed thermostabilizing system retards the thermal-oxidative degradation and makes it possible to obtain the polymer matrix with a thermal stability of 350–400°C.
