Herein, we report an iron(II)‐catalyzed polymerization of arylallenes. This reaction proceeds rapidly at room temperature in the presence of a hydride co‐catalyst to generate polymers of weight up to Mn=189 000 Da. We have determined the polymer structure and chain length for a range of monomers through a combination of NMR, differential scanning calorimetry (DSC) and gel permeation chromatography...
Comparison of the X-ray photoelectron spectroscopy (XPS) spectra for surfaces of Parylene C thin layers deposited on alumina substrates without heating or after various heating times at 150 °C revealed an increase in chlorine concentration near the surface with increasing heating time. After 200 h heating at 150 °C, the Parylene C layer flaked off of the alumina substrate. The deterioration of the...
