摘要
采用市售4种工业丝用超有光切片进行固相增粘(SSP)试验,研究了4种切片增粘速率、粘度增幅随时间变化的差异,通过反应动力学计算得到了试验条件下的表观反应速率常数,对动力学研究中的线性相关系数R^2进行了讨论。
The solid state polycondensation of some indusrial yarn grade PET chip was studied. Through analysis, we obtain the differences among the speed of SSP and △η of the four chip. Through dynamic calculation, the apparent reative speed constants were gained,R^2 were discussed at the same time.
