Popis:	The new alkoxysilane 2,2-bis(trifluoromethyl)-4,4-diethoxy-1-aza-3-oxa-4-silacycloheptane behaves as a bi- or trifunctional compound, depending on the hydrolysis conditions. In case of a deficiency of water, a mixture of cyclosiloxanes with cyclic substituents at silicon atoms is obtained, while in case of an excess of water, a crosslinked polysiloxane with hydroxyl-containing substituents is obtained. On the basis of the compositions 2,2-bis(trifluoromethyl)-4,4-diethoxy-1-aza-3-oxa-4-silacycloheptane and 3-aminopro-pyltriethoxysilane, under mild conditions in the presence of atmospheric moisture, transparent solid polysi-loxane coatings with very low refractive indexes for nonporous polymers are formed.
