The invention discloses a preparation method of poly (2-benzyl caprolactone). The method comprises the following steps: completing substitution of epsilon-caprolactone at low temperature under the action of a catalyst, and carrying out polymerization reaction under a heating condition to obtain poly (2-benzyl) caprolactone, so as to realize chiral substitution of poly (epsilon-caprolactone). Compared with polycaprolactone, the poly (2-benzyl caprolactone) obtained by polymerization has better thermal stability and mechanical properties, and the application range of the poly (2-benzyl caprolactone) product is greatly expanded. 本发明公开了一种聚2-苄基己内酯的制备方法。将ε-己内酯在低温和催化剂的作用下完成取代，在加热条件下进行聚合反应得到聚2-苄基己内酯，实现聚ε-己内酯的手性取代。聚合得到的聚2-苄基己内酯相较与聚己内酯具有更好的热稳定性和力学性能，极大扩展了聚2-苄基己内酯产品的应用范围。
