Synthesis, Characterization of Some New Dimer Nitrone Derivatives from Dapsone, Their Use as Initiators for Polymerization

Abstract

In order to address the demand for effective anionic initiators in polymerization processes, this work investigates the synthesis and characterisation of new dimer nitrone derivatives produced from dapsone. The aim is to close the existing gap in the acrylonitrile polymerization process by using nitrones as initiators. The process entails producing the necessary dimer nitrones by oxidizing with peroxy acid after generating dimer imines through condensation processes. Techniques including FTIR, 1H NMR, and MS were used to conduct the characterization. Evaluating these chemicals' potential as bulk polymerization initiators was the goal. The successful creation of polymers was revealed by the results, indicating that these dimer nitrones are efficient initiators of anionic polymerization, which may improve polymer synthesis techniques.
