The sol–gel polymerization and resulting structures of organic-inorganic systems based on hybrid methacrylate oligomers have been studied using SEC, DSC, and SAXS. The block and random oligomers with narrow polydipersity were prepared by group transfer polymerization. All the oligomers contain 3-(trimethoxysilyl)propyl methacrylates in the chain and form silsesquioxane (SSQO) clusters by hydrolytic polycondensation, serving as cross-linking domains of the organic-inorganic network.

Sol-gel polymerací byly syntetizovány organicko-anorganické systémy na bázi hybridních methakrylátů a jejich struktura byla studována pomocí SEC, DSC a SAXS. Blokové a statistické oligomery s úzkou distribucí molekulových hmotností byly připraveny group transfer polymeraci.
