Abstract
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 2,3-dihydroxypropyl ferrocene carboxylate and di-(2,3-dihydroxypropyl) ferrocene 1-1’-dicarboxylate, which are a diol and a diol, respectively. These compounds were characterized using FT-IR spectroscopy, 1H-NMR and 13C-NMR spectroscopy. These derivatives were incorporated into a commercially available polyol mixture at various weight percentages, mixed with methylene diphenyl diisocyanate, 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. Differential scanning calorimetry and volatile organic compounds testing were also performed on selected films. In addition, potential synergistic effects of the ferrocenyl polyols with triphenylphosphine oxide was studied. These materials were tested using the standard burn test chamber and thermal stability.
