The invention discloses a triblock polyester material as well as a synthesis method and application thereof. The invention belongs to the field of block polyester materials and synthesis thereof. The invention aims to solve the technical problem of generation of a random sequence caused by random transesterification. According to the invention, the triblock copolymer is synthesized through sequential transesterification reaction by utilizing the difference of transesterification capabilities of different polymers, so that the cyclic utilization of the waste polyester material is realized. The plastic pollution caused by the use of a large amount of polyester materials is reduced to a certain extent, the recycling of the plastic is realized, and a method for synthesizing a new material is provided. The method is suitable for recycling polyester products. The obtained triblock copolymer can be used as a thermoplastic elastomer after chain extension. 一种三嵌段聚酯材料及其合成方法和应用。本发明属于嵌段聚酯材料及其合成领域。本发明为解决随机转酯导致产生随机序列的技术问题。本
