  • Copolymers containing si-n and si-si bonds, polycarbosilazanes obtained by pyrolysis of the said copolymers, and use of the said polycarbosilazanes for the preparation of silicon carbonitride
    Patent number: 4992523
    Abstract: The present invention relates to copolymers containing --Si--N-- and --Si--Si-- bonds, which are obtained by the polycondensation ofat least one silane of the formula RR.sub.1 SiCl.sub.2and at least one disilazane of the formula ##STR1## in which formulae: R.sub.2 is a halogen atom, preferably Br and Cl, andR, R.sub.1 and R.sub.3, which are identical or different, represent a hydrogen atom or an alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, alkylaryl or alkenylaryl hydrocarbon radical which may be functional,to a process for the preparation of the said copolymers,to the polycarbosilazanes obtained by thermolysis of the said copolymers and to the silicon carbonitrides obtained by heating the said polycarbosilazanes.

  • Functional 1,3-dihydrogeno disilazanes
    Patent number: 4806666
    Abstract: The present invention relates to functional 1,3-dihydrogeno disilazanes of formula: ##STR1## in which: R and R.sub.1, identical or different, represent an atom of hydrogen or a hydrocarbon such as an alkyl, alkenyl or alkynyl, cycloalkyl or cycloalkenyl, aryl, alkylaryl, alkenylaryl, alkynylaryl, arylalkyl, arylalkenyl or arylalkynyl radical, possibly functional, R also being able to represent a radical ##STR2## and R.sub.2 represents an atom of halogen, an OR group or an --NRR.sub.1 group, when R and R.sub.1 are both hydrocarbon radicals.
