Description
The carbon fiber precursor production method that adopts Dimethyl Sulfoxide(DMSO) as the solvent, Acrylonitrile(AN) as the first monomer, Itaconic Acid as the second monomer, AIBN as the initiator to have a binary copolymerization, and the dry-jet wet spinning is the top choice agreed among carbon fiber experts.Tech Specs：
