The scope and accessibility of sequence-controlled multiblock copolymers is demonstrated by direct "in situ" polymerization of hydrophobic, hydrophilic and fluorinated monomers. Key to the success of this strategy is the ability to synthesize ABCDE, EDCBA and EDCBABCDE sequences with high monomer conversions (>98 %) through iterative monomer additions, yielding excellent block purity and low overall molar mass dispersities (Ð<1.16). Small-angle X-ray scattering showed that certain sequences can form well-ordered mesostructures. This synthetic approach constitutes a simple and versatile platform for expanding the availability of tailored polymeric materials from readily available monomers.
通过直接“原位”聚合疏水性、亲水性和含氟单体，展示了序列可控多嵌段共聚物的范围和可及性。该策略的成功关键在于通过迭代单体添加，以高单体转化率（>98%）合成 ABCDE、EDCBA 和 EDCBABCDE 序列的能力，从而获得出色的嵌段纯度和低总体摩尔质量分散度（Ð<1.16）。小角 X 射线散射表明，某些序列可以形成有序的介孔结构。这种合成方法为从现成单体扩展定制聚合物材料的可用性提供了一个简单而通用的平台。
