Web26 feb. 2024 · To prepare the ionic liquids, 1-methyl-1,2,3-benzotriazole was synthesized according to the method in the literature [ 33 ]. This compound was reacted with VBC to produce [ (MVb-Bt)Cl] which contains the chloride anion; its structure is shown in Scheme 1. It was identified by the 1 H-NMR and 13 C-NMR data. WebIt can generally be categorized into two types: free-radical polymerization (FRP) and controlled/living radical polymerization (CLRP). FRP enables the synthesis of high-molecular-weight polymers from a variety of monomers. FRP is a key synthesis route for obtaining a wide variety of different polymers and material composites. s2比心
