The Production of Fluorine-Containing Composite Materials Based on Polydieneurethane and Montmorillonite

The effect of organomineral complexes of 1,1,3-trihydroperfluoropropanol-1 (modifier) with layered aluminosilicate montmorillonite (LAM) as filler on the structure and properties of fluorine-containing polydieneurethane (FPU) was investigated. The modifier and the LAM were introduced into the FPU at the stage of its production. Using a combination of methods – X-ray diffraction analysis (DRON-3), electron microscopy (Versa 3D DualBeam, USA), and Fourier IR spectroscopy (Nicolet-6700, USA) – we studied features of the layer separation of LAM in the elastomer matrix as a function of the modifier concentration. It was shown that FPU specimens filled with LAM containing 5.0% polyfluorinated alcohol disintegrate better and possess a higher resistance to thermooxidative ageing.
