| Abstract: | In this article, the Surlyn® 8920 and AX 8900 were mixed as hybrid nucleating agents for glass fiber (GF)‐reinforced polyethylene terephthalate (PET)/polybutylene terephthalate (PBT) alloy. The crystallization behaviors on GF‐reinforced PET/PBT alloy with compound nucleating agents of Surlyn® 8920 and AX 8900 were studied by differential scanning calorimeter. The Jeziorny method, Mo method, and Kissinger method were used for studying the non‐isothermal crystallization process of the composite alloys. While single AX 8900 cannot further improve the crystallization properties of the alloy and reduced the crystallization rate, the introduction of Surlyn® 8920 can effectively ameliorate the condition. The results demonstrated the hybrid nucleating agents of Surlyn® 8920 and AX 8900 not only can accelerate crystal growth, but also can significantly reduce the energy barrier, and it has a good effect in the alloy to the nucleation.
