【Abstract】 The synthesis and properties of high molecular weight PAN fiber prepared by suspension polymerizaion using AIBN as the initiator were investigated systematically. The effects of different experiment conditions, such as suspension agent concentration, initiator concentration and temperature on the polymerization were discussed and the kinetic model for the reaction was established. The rheological property of high molecular weight PAN spinning solution was also studied.更多还原
