The Preparation and Thermodynamic Behaviors of Chlorosulfonated Polyethylene

The chlorosulfonated polyethylene (CSM)s with different content of chlorine and sulfurelements were prepared by aqueous solution suspension method. Prepared CSMs werecharacterized by Fourier transform infrared (FTIR) spectra. The thermal properties andcrystallization behaviors of the prepared CSMs were investigated by thermogravimetricanalysis (TGA) and differential scanning calorimetry (DSC), respectively. The degradationtemperatures of all the prepared CSMs exceeded 170 °C in air, which showed good thermalstability. The WAXD results indicated that the crystallinity of CSM decreased with theincrement of chlorine and sulfur content.
