Zhang, Wei published the artcileHighly Reactive Cyclic Carbonates with a Fused Ring toward Functionalizable and Recyclable Polycarbonates, Recommanded Product: Dimethyl fumarate, the publication is ACS Macro Letters (2022), 11(2), 173-178, database is CAplus and MEDLINE.
Monomer design plays an important role in the development of polymers with desired thermal properties and chem. recyclability. Here we prepared a class of seven-membered ring carbonates containing trans-cyclohexyl fused rings. These monomers showed excellent activity for ring-opening polymerization (ROP) with turnover frequency (TOF) up to 6 x 105 h-1 and catalyst loading down to 50 ppm, which yielded high-mol.-weight polycarbonates (Mn up to 673 kg/mol) with great thermostability (Td > 300°C). Ultimately, the resulting polycarbonates can completely depolymerize into their corresponding cyclic dimers that can repolymerize to synthesize the starting polymers in moderate yields, demonstrating a potential route to achieve chem. recycling. Post-functionalization of the unsaturated polycarbonate was conducted through crosslinking reaction and “click” reaction under UV irradiation
