Controlled Disassembly of Elemental Sulfur: An Approach to the Precise Synthesis of Polydisulfides

Ji-Yan Chao et al.

Summary: The usage of elemental sulfur for constructing sulfur-containing polymers is significant for sulfur resource utilization and fabrication of high-performance polymers. However, the random disassembly of elemental sulfur hinders its direct use in the precise synthesis of sulfur-containing polymers. This study provides an effective strategy for controlling the dismantlement of elemental sulfur to synthesize polydisulfides, a promising category of dynamic bonds containing polymers.

Alternating Copolymerization of Carbon Dioxide with Epoxides Using Highly Active Dinuclear Nickel Complexes: Catalysis and Kinetics

Yu-Chia Su et al.

Summary: A novel series of dinuclear nickel complexes containing benzotriazole based 1,3-diamine-bisphenolate (1,3-DiBTP) ligands were synthesized as highly active single component catalysts for the copolymerization of CO2 and epoxides. The best benzoate-bonded dinickel catalyst demonstrated effective activity for CO2-copolymerization of cyclohexene oxide at high pressure and 1 atm, achieving a high turnover frequency and producing narrowly dispersed poly(cyclohexene carbonate) with high selectivity. Additionally, kinetic studies of the copolymerization process revealed first-order dependence on catalyst and epoxide concentrations, with an activation energy of 57.69 kJ mol(-1) for poly(cyclohexene carbonate) generation.
