Podgorski, Maciej published the artcileThiol-Anhydride Dynamic Reversible Networks, Recommanded Product: Pentaerythritol tetra(3-mercaptopropionate), the main research area is thiol anhydride photopolymer stress relaxation dynamic network; covalent adaptable networks; dynamic composites; photopolymers; recycling; stress relaxation.
The reaction of thiols and anhydrides to form ring opened thioester/acids is shown to be highly reversible and it is accordingly employed in the fabrication of covalent adaptable networks (CANs) that possess tunable dynamic covalent chem. Maleic, succinic, and phthalic anhydride derivatives were used as bifunctional reactants in systems with varied stoichiometries, catalyst, and loadings. Dynamic characteristics such as temperature-dependent stress relaxation, direct reprocessing and recycling abilities of a range of thiol-anhydride elastomers, glasses, composites and photopolymers are discussed. Depending on the catalyst strength, 100% of externally imposed stresses were relaxed in the order of minutes to 2 h at mild temperatures (80-120°C). Pristine properties of the original materials were recovered following up to five cycles of a hot-press reprocessing technique (1 h/100°C).
