摘　　要：用GJY-3光学解偏振仪测定了PET、PP与PET/PP合金的结晶速度,并且在不同的结晶温度下比较了它们结晶速度的快慢。最后通过Avrami方程对PET/PP(3:1)合金进行了结晶动力学的研究。结果表明,其Avrmi指数为3。The crystallization rates of PET, PP and the blend based on PET and PP have been determined by means of GIY - 3 optical depolarized apparatus, and the crystallization rates of these samples at the different crystallization temperature have been compared. The crystallization kinetics have been investigated by the equation of Avrami. The results show that their Avrami Index are all approximately equal to 3.
