SILICON-BORON-CARBON-NITROGEN CERAMICS AND PRECURSOR COMPOUNDS, METHODS FOR THE SALT-FREE POLYMERIZATION OF RNHAL3-NSI - X - BRMHAL2-M

摘要

The present invention relates to novel methods for the salt-free polymerization of boron silyl amines, which have the structural characteristic Si-N-B, and boron hydrocarbonss, which have the structural characteristic Si-X-B, wherein X can be a methylene group or a hydrocarbon chain CxHy or a cyclic hydrocarbon unit, by reaction with disilazanes R3Si-NR-SiR3.
