The disclosure relates to a method of making carbon fiber, the method comprising pyrolyzing poly(p-phenylene) (PPP) fiber at a temperature sufficient to convert PPP fiber substantially to carbon fiber. The disclosure also relates to pre-PPP polymer, methods for making PPP fiber from pre-PPP polymer and, in turn, making carbon fiber from PPP fiber.
