Simple Amination of Polystyrene via Radical sp3 C-H Imination

Abstract

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.
