Abstract
Two linear polysiloxanes with vinyl groups regularly distributed in their chains (D2V polymer with a vinyl group at every third and V3 polymer with a vinyl group at each Si atom) were cross-linked with different hydrogensiloxanes (linear difunctional HMMH, linear branched tetrafunctional Q(MH)4, cyclic tetrafunctional D4 H) and studied as new precursors to SiCO ceramics. It was found that thermal properties of the cross-linked D2V and V3 polymers are governed mainly by functionality of the initial macromolecule as well as functionality and molecular structure of hydrogensiloxane. Transformation of the systems into ceramics was examined by recording FTIR spectra of the samples obtained after heat treatment of the cross-linked polymers under Ar at several temperatures. Analysis of the products formed at 1000°C, allowed establishing that they are a mixture of silicon oxycarbides and a free carbon phase. Lack of pores is a characteristic feature of these materials. © 2013 Elsevier Ltd.
