## Abstract Ammoniumβmodified polyacrylonitrile was prepared by freeβradical solution copolymerization of acrylonitrile (AN) with ammonium itaconate (AIA), and then it was spun into precursor fibers in this study. Effects of AIA and itaconic acid on the characteristics of the copolymers and precurs
The development of fine structure in PAN-based carbon fibres prepared in the temperature range 300Β°C to 1000Β°C will be discussed in terms of X-ray and electron microscope results, including direct lattice resolution. Further evidence on high-modulus carbon fibres treated around 28OO"C, and a three-d
