The invention relates to a method for preparing a biodegradable elastomer. Epoxidized natural rubber reacts with carbon dioxide under high pressure to generate polyisoprene containing cyclic carbonate and polycarbonate, and the elastomer is endowed with biodegradability based on a weak bond introduction strategy. Compared with the existing elastomer, the prepared elastomer has the advantages that the biodegradability is improved, and a new way is opened up for solving the problem of black pollution of the elastomer. 本发明涉及一种可生物降解弹性体的制备方法。通过高压下环氧化天然橡胶与二氧化碳反应生成含环碳酸酯和聚碳酸酯的聚异戊二烯，基于引入弱键策略赋予弹性体可生物降解性。与现有的弹性体相比，本发明制备弹性体改善了生物降解能力，为解决弹性体的黑色污染问题开辟了新的道路。
