Beschreibung
Zusammenfassung:	The invention belongs to the technical field of elastomer synthesis, and particularly discloses a long-carbon-chain polyamide elastomer as well as a preparation method and application thereof. The long-carbon-chain polyamide elastomer meets the requirements that the relative viscosity is 3-4, the Tm is 150-180 DEG C, the long-carbon-chain polyamide elastomer is suitable for foaming after being melted and mixed with an AC foaming agent while the heat resistance of the material is guaranteed, the foaming ratio is larger than 8, and the shore hardness is larger than 45. 本发明属于弹性体合成技术领域，具体公开一种长碳链聚酰胺弹性体及其制备方法和应用。本发明的长碳链聚酰胺弹性体满足相对粘度为3-4，Tm为150℃-180℃，其能在保证材料耐热性能的同时，适合用于与AC发泡剂熔融混合后进行发泡，发泡倍率大于8，邵氏硬度大于45。
