Synthesis, characterization and properties of poly(methylenetetrasulfide) using interfacial catalysis
- 59 Downloads
A new polysulfide polymer was synthesized from methylene dichloride and sodium tetrasulfide by an interfacial polycondensation technique using two quarternary ammonium salts as phase transfer catalysts. The synthesized polymers were characterized by FT-IR, X-ray and elemental analysis. Thermal properties were evaluated by thermogravimetric analysis and differential scanning calorimetry. The solvent resistance of the polymer was investigated by the swelling method.
