## Abstract Monomer reactivity ratios of acrylonitrile/ammonium itaconate during aqueous‐deposited copolymerization initiated by ammonium persulfate were investigated. Kelen–Tudos method was used to examine the reactivity ratios. It was shown that the reactivity ratios were influenced by the conver

## Abstract Aqueous deposited copolymerization reactions of acrylonitrile (AN) with itaconic acid (IA) were carried out in deionized water at 60°C with a single water‐soluble initiator. High‐molecular‐weight polyacrylonitrile (PAN) copolymers were acquired by adjustment of technical polymerization
## Abstract Ammonium‐modified polyacrylonitrile was prepared by free‐radical 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
