Abstract The monomers composition and molecular chain structures of PLV85540 fluoroelastomer were systematically analyzed and investigated by attenuated total reflectance/Fourier transform infrared (ATR-FTIR),¹H nuclear magnetic resonance (NMR),¹⁹F-NMR spectroscopy and gel permeation chromatography (GPC); thermal properties of it was experimentally measured by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) in this paper. Based on these analyses and calculations, we clearly defined its microstructures and effect of fluoroether monomer on its thermal properties. The results revealed that PLV85540 is a kind of five-membered copolymer, which composites by vinylidene fluoride (VDF), tetrafluoroethylene (TFE), perfluoromethyl vinyl ether (MVE), perfluoroalkoxy vinyl ether (MOVE) and the cure site monomer (c.s.m, contain double bond). After calculations, it can be seen that the VDF content is about 57.3%, the TFE content is about 20.5%, the MVE content is about 6.5%, the MOVE content is about 15.6% and c.s.m content is about 0.1%. Due to the addition of MOVE, the low temperature resistance of PLV85540 is further improved, and the glass transition temperature is about -40 ℃. At the same time, since the chain structures is not been destroyed, the thermal stability is maintained and its thermal decomposition temperature is about 430 ℃.
