Cu(0)-RDRP is a powerful technique to synthesise a wide range of polymeric materials and architectures with controlled molecular weight, low dispersities and high end group fidelity. The vast majority of reports using this technique focus on the polymerisation of acrylates or methacrylates, with very limited examples on styrene, which is surprising as this is one of the most important vinyl monomers. Herein we present the first Cu(0)-wire mediated polymerisation of styrene with enhanced initiator efficiency and dispersity. The structure of the ligand, the type of the initiator, the nature of the solvent and the catalyst concentration have been systematically varied to afford polystyrene at relatively high molecular weights (∼50 000 g mol⁻¹) with excellent agreement between theoretical and experimental number average molecular weight values and good control over the molecular weight distributions (Đ ∼ 1.15).

苯乙烯的Cu（0）-RDRP：平衡引发剂效率和分散度†

Cu（0）-RDRP是一种功能强大的技术，可以合成分子量范围可控，分散度低和端基保真度高的多种聚合物材料和结构。使用该技术的绝大多数报道都集中在丙烯酸酯或甲基丙烯酸酯的聚合上，在苯乙烯方面的例子非常有限，这是令人惊讶的，因为这是最重要的乙烯基单体之一。在这里，我们介绍了具有增强的引发剂效率和分散性的苯乙烯的第一个Cu（0）线介导的聚合反应。系统地改变了配体的结构，引发剂的类型，溶剂的性质和催化剂的浓度，以提供相对较高的分子量（约50,000 g mol ^-1）的聚苯乙烯）与理论数均分子量和实验数均分子量之间的一致性极佳，并且对分子量分布的控制良好（Đ〜1.15）。
