Modern Approaches to Obtaining Organofunctional Silsesquioxanes

Modern research in the field of synthesis of organofunctional oligosilsesquioxanes is considered. Relationships between the composition and structure of oligomeric organosilsesquioxanes and the conditions for their formation during the hydrolytic and acidohydrolytic polycondensation of organotrialkoxysilanes containing various functionalities, such as methacrylic, aminopropyl, carboxyl, and cyclotriphosphazene groups, in organic radicals bonded to silicon atoms are shown. A comparative analysis of approaches to the synthesis of organofunctional incompletely condensed oligosilsesquioxanes has been carried out.
