Abstract

The application of the sol-gel process for the formation. of inorganic-organic composites has received a great deal of attention in recent years. We have focused our efforts in this area toward the development of simultaneous polymerization/sol-gel reactions for the developement of inorganic-organic composites with a wide range of polymers. Further research in this area has led to the design and synthesis of tetraalkoxysilanes, and more recently, poly(silicic acid esters) possessing polymerizable alkoxides for the synthesis of non-shrinking sol-gel composites.

8. Equation 2 is derived by noting that the percent glass in the final material is a function of the weight percent glass contributed by each silicon center (Q2, Q3, and Q4) and that the amount of glass is reduced by the alkoxide substitution ( two alkoxides per Q2 center and one alkoxide per Q3 center).Google Scholar
