| 摘 要： | 采用溶液法制备苯乙烯-甲基丙烯酸钠(SMA-Na)离聚物，研究其对聚对苯二甲酸乙二酯（PET）的结晶及熔融行为的影响。结果表明：SMA-Na是PET的良成核剂，加入1wt %的苯乙烯-甲基丙烯酸钠使PET的熔融结晶温度（Tmc）提高了17.9 ℃，冷结晶温度(Tcc)降低了17.3℃，显著的提高了PET在高温区和低温区的结晶速度。加入离聚物，使得PET球晶变得更加细化完善。

| Abstract: | Styrene-Sodium Methacrylate(SMA-Na) was synthesized by solution technique.The effect of ionomer on crystallization and melting behaviors of polyethylene terephthalate(PET) was investigated.The results show that with the addition of 1wt% SMA-Na ,the the Tmc of PET increased 17.9℃, and the Tcc decreased 17.3℃,accelerating the crystallization rate of PET both at high temperature region and low temperature region. The spherulites of PET/ SMA-Na Composites was more perfect than neat PET. |
