Abstract

The increasing interest in inorganic-organic nanocomposites which offer the possibility to build up both an inorganic and organic network by hydrolysis and condensation and by polymerization reactions, respectively, leads to the development of a new class of double bond functionalized silanes. These 2-vinylcyclopropyl silanes were synthesized e.g. by reaction of 1-methoxycarbonyl-2-vinylcyclopropane-l-carboxylic acid with 3-isocyanatopropyltriethoxysilane. Hydrolysis and condensation of the alkoxy groups as well as cocondensation with tetraalkoxysilanes lead to solvent-free liquid resins that can be cured by UV-light-induced radical polymerization of the vinylcyclopropane group. The synthesis and characterization of different 2-vinylcyclopropyl silanes, hydrolysation and condensation behavior and first results of the radical polymerization will be discussed.
