We report the mild functionalization of polystyrene with primary amines and other nitrogen groups through sp³ C–H imination. This process significantly increases hydrophilicity without deterioration of molecular weight or thermal properties, and provides a handle for further covalent modification. This work will enable the upcycling and diversification of commodity polyolefins.

通过自由基 sp3 C-H 模拟对聚苯乙烯进行简单的胺化反应


我们报道了聚苯乙烯通过 sp³ C-H 模拟与伯胺和其他氮基团的轻度官能化。该工艺显著提高了亲水性，而不会降低分子量或热性能，并为进一步的共价修饰提供了处理方法。这项工作将使商品聚烯烃的升级回收和多样化成为可能。
