Ferrocene containing polyurethanes for improved flame-retardant properties
Flame retardant polyurethanes are needed for various commercial and industrial applications; toward that end ferrocene derivatives with multiple hydroxyl groups were synthesized for incorporation into polyurethane thin films for testing. The derivatives synthesized were di-(2,3-dihydroxypropyl) ferrocene 1 – 1 –dicarboxylate and 2,3-dihydroxypropyl ferrocene carboxylate. These compounds were characterized using FT-IR spectroscopy, 1 H-NMR and 13C-NMR spectroscopy. These derivatives were incorporated into a commercially available polyol mixture at various weight percentages, mixed with toluene di-isocyanate, and cast as thin films on glass plates. Each film was tested for flame retardance using a standard burn test chamber and thermal stability in both nitrogen and air. Volatile organic compounds testing were also performed on selected films. In addition, potential synergistic effects of the ferrocenyl polyols with triphenyl phosphine was studied.
