제목 Synthesis of Sustainable Polythionoesters via Ring-Opening Polymerization of Thionolactones Using Heterogeneous Catalysts
초록 The utilization of sustainable polymers aims to address the environmental challenges that are inherently associated with traditional petroleum-based polymers by using sustainable and renewable feedstocks. Thionolactones synthesized from lactones by S/O substitution attracted attention owing to the crosslinking nature and subsequent biodegradability and metal recovery application. Here we have synthesized thionolactones and utilized them for the ring-opening polymerization (ROP) and subsequent investigation of its kinetics. Anhydrous ethylene glycol is used to initiate the ROP of thionolactones in the presence of a heterogenous catalyst. Monomers and polymers were characterized using proton nuclear magnetic resonance spectroscopy, Fourier-transform infrared spectroscopy, and gel permeation chromatography. The kinetic studies indicate that the reaction rate is first-order with respect to the concentration of monomer and initiator.
