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.
