Abstract

Functionalized silsesquioxanes containing from 6 to 24 silicon atoms and minimally about 67 mol percent RSiO3/2 moieties where R is a phenyl group bearing a chemically reactive functional group are highly suitable for use as nanoparticles in producing highly ordered nanocomposites of many types, containing a high proportion of interphase. The nanocomposites have unusual physicochemical properties due to the use of uniform, highly functionalized nanoparticles.
