金属催化配位插入聚合是制备聚烯烃最广泛使用的方法之一，聚烯烃是一类广泛的聚合物，占合成材料市场的绝大多数。为了更好地控制聚合过程，化学家们开发了创新的策略，通过反应工程（例如，改变温度、压力、溶剂等）或引入外部刺激（例如，氧化还原试剂、光、硼烷或金属阳离子）来调节催化剂。这篇综述文章将提供各种可调模式的概述，用于调节烯烃的聚合过渡金属配合物。我们将专注于各种方法的独特功能和局限性，并就外部调节聚合如何对应用和未来研究产生有意义的影响提供我们的观点。
Metal-catalyzed coordination insertion polymerization is one of the most widely used methods to prepare polyolefins, a broad class of polymers comprising a vast majority of the synthetic materials market. To impart greater control over the polymerization process, chemists have developed innovative strategies to enable catalyst tuning by reaction engineering (e.g., changing temperature, pressure, solvent, etc.) or introducing external stimuli (e.g., redox reagents, light, boranes, or metal cations). This review article will provide an overview of the various tunable modalities employed to regulate the polymerization of olefins by transition metal complexes. We will focus on the unique capabilities and limitations of various approaches and offer our perspective on how externally regulated polymerization could have meaningful impacts on applications and future research.
