Abstract
The kinetics of the condensation polymerization of a novel polysulfide polymer based on methylene dichloride and sodium tetrasulfide is studied. The results of the experiments indicated that the reaction order is two. The activation energy obtained from the Arrhenius plot is 1.879 kcal mol−1, and the pre-exponential frequency factor is A = 27.11 min−1 at temperature range of 40∼60°C. The polymer is characterized by using Fourier transform-infrared and CHN analysis. Thermal properties were evaluated by differential scanning calorimetry. The TGA-DTA was used to find out the thermal stability of polymer. The solvent resistance of the polymer was investigated by the swelling method.
