摘要 聚合取代环氧化物（尤其是环氧丙烷）的传统方法存在副反应，严重限制了所得聚环氧丙烷（PPO）的摩尔质量和端基控制。这不仅使 PPO 部分融入复杂的聚合物结构变得复杂，而且还阻碍了 PPO 本身作为一种有趣材料的考虑。在此背景下，提供了创建真正高分子量聚醚的策略的简明摘要，重点是最近开发的双催化装置，该装置允许获得 106 g/mol 及以上的 PPO 摩尔质量。基于聚醚催化制备方面的这些进展，确定了超高分子量 (UHMW) PPO 作为高性能材料的未来前景。
Abstract Conventional approaches for polymerizing substituted epoxides, especially propylene oxide, suffer from side reactions, severely limiting molar masses and control over the end groups of the resulting poly(propylene oxide) (PPO). This has not only complicated the incorporation of PPO moieties into complex defined polymer architectures, but has also hampered consideration of PPO as an interesting material in its own right. In this context, a concise summary of strategies for creating truly high-molecular-mass polyethers is provided, with a focus on a recently developed dual catalytic setup that permits access to PPO molar masses of 106 g/mol and beyond. Based on these advances in the catalytic preparation of polyethers, future perspectives for ultrahigh-molecular-weight (UHMW) PPO as a performance material are identified.
