Embodiment 1

[0345] Formulate polysilocarb formulations using a hybrid approach. The formulation was prepared by mixing 41% MHF and 59% TV at room temperature. The precursor formulation has 0.68 moles of hydrogen, 0.68 moles of vinyl and 1.37 moles of methyl groups. The precursor formulation has the following molar amounts of Si, C and O based on 100 g of formulation.

[0346]

[0347] According to calculations, the SiOC derived from the formulation had a calculated 1.37 moles of C with 0% excess C after all CO had been removed.

Embodiment 2

[0349] Formulate polysilocarb formulations using a hybrid approach. The formulation was prepared by mixing 90% methyl terminated phenylethyl polyoxysilane (with 27% X) and 10% TV at room temperature. The precursor formulation has 1.05 moles of hydrogen, 0.38 moles of vinyl, 0.26 moles of phenyl and 1.17 moles of methyl groups. The precursor formulation has the following molar amounts of Si, C and O based on 100 g of formulation.

[0350]

[0351] According to calculations, the SiOC derived from the formulation would have a calculated 2.31 moles of C with a 98% excess of C after all the CO had been removed.

Embodiment 3

[0353] Formulate polysilocarb formulations using a hybrid approach. The formulation was prepared by mixing 70% methyl terminated phenylethyl polyoxysilane (with 14% X) and 30% TV at room temperature. The precursor formulation has 0.93 moles hydrogen, 0.48 moles vinyl, 0.13 moles phenyl and 1.28 moles methyl. The precursor formulation has the following molar amounts of Si, C and O based on 100 g of formulation.

[0354]

[0355] According to calculations, the SiOC derived from the formulation would have a calculated 1.77 moles of C with a 38% excess of C after all the CO had been removed.
