Zusammenfassung:The present disclosure discloses a semi-aromatic polyamide and a preparation method therefor. The semi-aromatic polyamide is obtained by polymerization reaction using a diamine, a dibasic acid and a monoacid as main raw materials while adding a special end-capping agent. The semi-aromatic polyamide prepared according to the present disclosure has good thermal stability, a yellowness index of less than 20, a glass transition temperature of 90° C. or above, and a melting point of 300° C. or above, and can be applied to spare parts for fuel pipelines in automobiles, and electronic and electrical industries such as LED panels.
