Di-olefin monomers

Figure 10. Hydrosilation Polymerization of TFVE Di-olefin Monomers.

Thermal stability in nitrogen exceeded 400°C in most network cases which is characteristic of both siloxane and PFCB containing materials. Not shown here is the thermal oxidative stability for thermosets 11 -14 . In contrast to the TFVE reactive polymers prepared from mono-olefin TFVE derivatives, networks 11 -14 prepared from TFVE functionalized di-olefin monomers do not contain oxidatively unstable benzylic carbons.
