Simple upcycling of virgin and waste polyethylene into covalent adaptable networks: catalyst-free, radical-based reactive processing with dialkylamino disulfide bonds

Abstract

For the first time, virgin and waste polyethylene (PE) was upcycled using exclusively free-radical methods into reprocessable, thermally stable, and creep-resistant PE covalent adaptable networks capable of dialkylamino disulfide dynamic chemistry.
