Organosiloxazanes –A New Line of Advance in the Chemistry of Hetero-organic Oligomers and Polymers

Organosiloxazanes synthesised by the beginning of 1977 have been classified for the first time (according to their structure and molecular weight). For each of the three main groups – (1) cyclic, (2) linear and cyclolinear, and (3) polymeric – the main methods of preparation and the physicochemical characteristics are surveyed. In conclusion several fields of practical application of the new compounds and materials based on them are considered. A list of 114 references is included.
