The pyrolysis processes of poly(isopropyliminoalane) ((HAlN i Pr) 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), (HAlN i Pr) 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 (HAlN i Pr) 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.
