摘要：
In the present work, the mechanochemical synthesis of polyboronphenylsiloxanes was carried out. Boron difluoride acetylacetonate and polyphenylsilsesquioxane were used as starting reagents. The products of the syntheses were studied by IR and NMR spectroscopy, elemental and X-ray phase analysis, gel permeation chromatography and MALDI-TOF/TOF-MS. The composition of the obtained products was determined established. It is shown that the fluorine radical released as a result of mechanical activation, as well as air humidity, plays a major role in the formation of products.
