The Main-Chain Structure and Chlorine Distribution of Chlorosulfonated Polyethylene via Gas-Solid Phase Method

Abstract:

The main-chain structure and chlorine distribution of chlorosulfonated polyethylene (CSM), which was prepared via gas-solid phase method, were studied in this article. All the structure types of CSM 3550 and CSM 3570 were completely characterized by Nuclear Magnetic Resonance (NMR). According to the ¹H NMR and ¹³C NMR spectra, the chlorine content (Cl wt %) and sulfur content (S wt %) of CSM 3550 and CSM 3570 could be completely calculated and this value was much close to the theoretical values, which were provided by the manufacturer. The comparison shows that the chlorine distribution of CSMs via gas-solid phase method is more uniform than that of CSMs via solution method.
