Conclusions

  1. 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. 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.
