Recyclable Thiol-ene Polymers via Thiol-Disulfide Exchange Reaction

The basis of this project is a reprocessable photopolymer made up of a UV-induced thiol-ene network. The introduction of a tetra functional thiol into the structure, pentaerythritol tetrakis (PETMP), improves the mechanical and thermal properties of this network while also maintaining the disulfide backbone, which allows for reprocessing. These properties are evaluated using tensile testing, degradation trials, and rheometry.
