The Silica-Polymer Composites of the System of HEMA-TEOS: The Synthesis, Thermomechanical Properties, and the Features of the Kinetic of the Process

214Hybrid organic–inorganic composites (HOIC), based on 2-hydroxyethylmethacrylate-tetraethoxysilane system in a wide range of the composition system changes, were obtained by the methods of sol-gel synthesis and photoinitiated polymerization. The kinetics of photoinitiated polymerization of the obtained composites depending on time of gelation has been studied. The influence of the HOIC composition on their thermomechanical properties and parameters of their molecular structure was investigated.
