Polyacrylonitrile (PAN) polymers with low polydispersity index (PDI) and carbon fibers made therefrom

A method for synthesizing polyacrylonitrile (PAN) polymer with a narrow molecular weight distribution is disclosed. The preferred PAN polymer has a PDI (Mw/Mn) of about 2 or less. Such PAN polymer is synthesized by controlled/living radical polymerization using a special RAFT (Reversible Addition-Fr...
