Abstract:

As a high-performance, multi-purpose biodegradable material, aliphatic polyester is considered to be one of the attractive alternatives to petroleum-based polymers. However, they often suffer from drawbacks, such as hydrophobicity and brittleness due to their single structure nature, which limits its application in biomedical and pharmaceutical industries. Thus, the modification of polyester is of great theoretical significance and practical application, of which one efficient way is to incorporate the aliphatic polyethers segments into the main chain of polyesters. Herein, this review aims to describe the synthesis of polyester-polyether copolymers by the copolymerization of lactones and epoxides, including random, block, and alternating copolymers.

Key words: epoxide, lactone, polymerization, polyester-polyether copolymer, synthesis, catalysis

摘要:

脂肪族聚酯作为一种高性能、多用途的生物可降解材料,被认为是具有吸引力的石油基聚合物替代品之一。现有的脂肪族聚酯存在的结构单一、亲水性差以及脆性较强等缺点,限制了其在医药卫生等领域的应用。因此,高效地实现聚酯的改性具有重要的理论研究意义和实际应用价值。其中,将醚类官能团与酯链段相结合得到聚醚-聚酯共聚物是提高聚酯性能的一类行之有效的改性方法。本文综述了内酯和环氧烷烃共聚合成聚酯-聚醚共聚物的研究进展。以共聚物的主链序列分类,分别介绍了嵌段、无规以及交替共聚物的合成方法以及相应聚合物的性质和性能。
