摘要：
The topological structure of epoxy-siloxane composites prepared by anhydride curing was studied in relation to the molar ratio of glycidoxypropyltriethoxysilane and tetraethoxysilane and to the total content of siloxane components of the system. The optical characteristics, glass transition point, sol fraction yield, concentration of internodal chains, and maximal rate of oxygen uptake by the hybrid materials were determined.
