With zinc D, L-lactate as catalyst, which is safe to body, PDTC with Mw as 700000g/mol was prepared when the reaction mixture was irradiated for 75min under 180W microwave power. This method was proved to be ideal for preparing PDTC with high molar mass.

• 作者使用对人体安全可靠的D，L-乳酸锌为催化剂，进行DTC的微波开环聚合，在180W的微波功率下辐照75min，得到了重均分子量为700000g/mol的PDTC，这一方法是合成高分子量PDTC的理想方法。
