Abstract: One-step method for the preparation of polyphenylsilsesqui oxane by condensation of all-cis-1,3,5,7-tetraphenyl-1,3,5,7 tetrahydroxycyclotetrasiloxane in liquid ammonia has been developed. This method makes it possible to produce high molecular weight polymers with regular structure in the absence of organic solvent. The structure of the polymer product was confirmed by ¹H and ²⁹Si NMR spectroscopy, GPC, IR spectroscopy, powder X-ray diffraction and viscosimetry.
