Abstract:
Co-polymers, made of two or more different monomer units, are classified by monomer arrangement. Random co-polymers have monomers distributed irregularly, while block co-polymers contain long, uniform segments. Differentiating between these types is crucial for applications in material science, where the specific arrangement of monomers can significantly influence the material's properties and performance. This study explores the application of ESI (Electrospray Ionization)-EAD (Electron-activated dissociation)-TOF (Time-of-flight) mass spectrometry for differentiating random and block copolymers. EAD generates unique fragmentation patterns, offering comprehensive structural insights. Our findings highlight the potential of EAD to enhance the accuracy and reliability of co-polymer characterization.
