Polyethylene (PE) is a ubiquitous commodity polymer that faces significant barriers to efficient recycling despite its thermoplastic nature. PE can be permanently cross-linked to enhance its properties and expand its...

Ethylene-based copolymers such as ethylene/1-octene copolymers (EOCs) are commonly used in blends for thermoplastic elastomers, foams, and consumer articles. These blends may be permanently cross-linked to enhance elasticity at the...

Conventional cross-linked polymers or thermosets cannot be melt-processed because of their permanent cross-links. Covalent adaptable networks (CANs) with covalent cross-links that are dynamic under a stimulus allow for reprocessing. Disulfide...
