Ultra-high molecular weight polyacrylonitrile (UHMWPAN) powders were synthesized by aqueous suspension polymerization with different AN/IA ratios using α,
Acrylonitrile (AN) and itaconic acid (IA) were used to synthesize UHMWPAN by aqueous suspension method with 2,2-azobisisobutyronitrile (AIBN) as the initiat
