| Abstract: | The glass transition temperatures （Tg） of four polyacrylonitrile fibers were determined by means of differential scanning calorimetry（DSC） with two step heating program at 10℃/min heating rate.The heating range was from 30℃ to 150℃.We studied the test conditions of the heating method and the sample weight so that we got the accuracy and reliable glass transition temperature. |
