Conclusions
-
1.
In the reactions of cyclosilazoxanes with alkali at above 100° ammonia and methane are liberated, and the curve expressing the change in viscosity has a well-defined maximum.
-
2.
At the first stage of the reaction the cyclic compound polymerizes with opening of the ring, which leads to increase in the viscosity of the system. At the second stage fragmentation of the polymer chains with liberation of ammonia predominates, which leads to a fall in viscosity.
