Herein we report a polymerization-induced self-assembly (PISA) process with ring-opening metathesis polymerization (ROMP). We utilize a peptide-based norbornenyl monomer as a hydrophobic unit to provide a range of nanostructures at room temperature yet at high solids concentrations of 20 wt % in combination with an oligoethylene glycol based norbornenyl monomer. Evaluation of the polymerizations under mild conditions highlight that good control is maintained along with high monomer conversion of greater than 99%, indicating that the living polymerization is unaffected during the PISA process. The demonstration broadens the scope of the PISA process to a new living polymerization methodology toward the development of easily accessible and highly functionalized nanostructures in situ.
在此，我们报道了一种采用开环易位聚合（ROMP）的聚合诱导自组装（PISA）过程。我们使用基于肽的降冰片烯基单体作为疏水单元，在室温下且在20 wt%的高固体浓度下，与基于低聚乙二醇的降冰片烯基单体结合，提供一系列纳米结构。在温和条件下对聚合反应的评估表明，聚合反应得到了良好的控制，单体转化率高于99%，这表明在PISA过程中活性聚合不受影响。这一示范将PISA过程的范围扩展到一种新的活性聚合方法，以原位开发易于获得且功能高度化的纳米结构。
