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.

ROMPISA：开环复分解聚合诱导的自组装

在这里，我们报告了具有开环复分解聚合 (ROMP) 的聚合诱导自组装 (PISA) 过程。我们利用基于肽的降冰片烯单体作为疏水单元，在室温下与基于低聚乙二醇的降冰片烯单体结合，在 20 wt% 的高固体浓度下提供一系列纳米结构。在温和条件下对聚合反应的评估强调了良好的控制以及大于 99% 的高单体转化率，这表明活性聚合在 PISA 过程中不受影响。该演示将 PISA 过程的范围扩大到一种新的活性聚合方法，以原位开发易于获得和高度功能化的纳米结构。
