The present disclosure provides a polymeric composition resistant to temperatures comprising Poly 2,5rBenzimidazole having intrinsic viscosity (I.V.) between 1.0 and 2.5; and at least one binder having a glass transition temperature less than the glass transition temperature of Poly2,5-Benzimidazole and intrinsic viscosity ranging between 0.2 and 1.5. The present disclosure also provides a process for preparing the polymeric composition resistant to temperatures.
