Description
Summary:	The results of vibrational spectroscopy and X-ray diffraction obtained at the present level of the methods confirm the planar trans ( all -A) conformation of the polydimethylsilane chain recently called in question. The differential scanning calorimetry data also verify the first order phase transitions at about –35 and 145 °C which proceed with retention of the all -A chain conformation and are of order-disorder type.
