Abstract
Polymers such as phenyltrimethoxysilylterminated polystyrene are prehydrolyzed and then condensed with a metal alkoxide using acid catalyzed sol-gel reactions. The product is an organic/inorganic composite in which a metal polycondensate core is covalently bonded to a plurality of organic arms. The core has more metal atoms than heretofore obtainable. The process of this invention provides a means for introducing an inorganic phase into an organic polymer and maintaining solubility of the resulting composite in organic solvents. The products of this invention have a larger organic phase than products discussed in the literature. They also have residual chemical reactivity.
