SILICON-BORON-CARBON-NITROGEN CERAMICS AND PRECURSOR COMPOUNDS, METHODS FOR THE SALT-FREE POLYMERISATION OF RnHal3-nSi-X-BRmHal2-m

摘要

The present invention relates to novel methods for the salt-free polymerisation of borosilylamines, which comprise the structural feature Si—N—B and borosilyl hydrocarbons, which comprise the structural feature Si—X—B, wherein X may be a methylene group or a hydrocarbon chain C_xH_y or a cyclic hydrocarbon unit, by reaction thereof with disilazanes R₃Si—NR—SiR₃.
