Abstract: The present invention relates to covalent adaptable networks (CANs) having exchangeable crosslinks that are able to undergo repeated covalent bond reshuffling through photo-activation at ambient temperatures. The invention provides covalent adaptable network forming compositions as well as methods of forming, remolding and recycling the CANs of the invention.

Abstract: Described herein is a composition for producing a thiol-ene covalent adaptable network (CAN) polymer. The composition includes a first monomer including at least one thiol group; and a second monomer including at least one anhydride functional group and at least one alkene functional group. Also described herein are a polymer produced from the composition, a method of producing the polymer using the composition, a method of fabricating a polymer article using the composition, as well as a method of degrading the polymer.
