Abstract: The PAN pelletizing principle and the effect of different surfactants on PAN polymer particles' performance of wetting, solidifing, water and powder quantity,heat resistance, strength and length were studied. A new TFX-2000 PAN pelletizing agent was prepared from polyether,ester,phosphate and other special chemical agents,such as the infiltrative, the water reduce agent, the solidified agent, the coagulant.The performances of PAN pelletizing agent were also studied.
