Abstract
Silicon oxycarbide is a material with a number of advantageous properties that strongly depend on its structure. The most common approach to its tailoring is based on varying the silicon to carbon atoms ratio in the preceramic polymeric precursor. This work is the first comparison of the materials obtained from precursors with the same Si to C atoms ratio, but with various distribution of these atoms in the preceramic polymer. In addition to standard mixtures of monomers containing single silicon atom, a number of monomers with high molar masses and well defined structure was used. The IR was used to investigate the structure of the precursors and materials obtained after their annealing in 800 degrees C. The results show, that not only the distribution of carbon containing groups among the monomers is important, but also the (in)ability of these groups to end up in each other vicinity in the precursor as well as the degree of condensation of each structural unit.
