Conclusions
-
1.
The structure of the chains of molecules of oligomers of the silico- and titanomethylphenylsiloxane series has a great influence on the vitrification point, thermal stability, and viscosity of the oligomers.
-
2.
Oligomers with branched chains of the molecules, containing various groups at the ends of the chains, possess lower thermal stability in isothermal ageing than oligomers with a spirocyclic molecular structure.
