N2 - The pyrolysis processes of poly(isopropyliminoalane) ((HAlNiPr)n) were investigated, using mass spectrometry to analyze the gases and infrared spectroscopy to analyze the residual solids. The major mass loss (in the temperature range of 240°-540 °C) consisted of two different pyrolysis stages. At the first stage (240°-320 °C), (HAlNiPr)6 was detected continuously as a gas, and the precursor was converted to a cross-linked structure. A polymerization mechanism without a release of organic compounds has been proposed, and the formation of (HAlNiPr)6 during polymerization (besides its evaporation) has been suggested. The second stage (320°-560 °C) involved the formation of various organic compounds, and radical processes for their formation were proposed.
