Problems solved by technology

[0004] More or less, all of these materials and the methods used to make them have one or more disadvantages, including: for example, they are prohibitively expensive and difficult to prepare, with costs in the tens of thousands of dollars per pound; they require high or very high Purity of starting materials; these methods require hazardous organic solvents, for example, toluene, tetrahydrofuran (THF) and hexane; these materials cannot prepare non-reinforced structures with any usable strength; these methods produce undesired and Harmful by-products such as hydrochloric acid and sludge, which may contain magnesium; these methods require multiple solvents and reactants based on reaction steps combined with curing and pyrolysis steps; these materials do not form useful prepreg materials; and All their physical properties are mixed, for example, excellent temperature characteristics but very brittle
[0005] Thus, although believed to hold great promise, these types of materials have not found widespread application or market acceptance, and remain largely at the stage of scientific exploration

Embodiment 1

[0241] Formulation of polysilocarbonate formulations obtained using a hybrid approach. The formulation is prepared by mixing 70% of such as figure 1 The MHF precursor shown by the molecular formula and having a molecular weight of about 800 and 30% of such as Figure 5 Allyl-terminated precursors of the formula shown and molecular weights of about 500 were prepared by mixing together in a container and stored for later use. The polysilocarb formulation has a good shelf life at room temperature and the precursors do not and do not react with each other. The polysilocarb formulation has a viscosity of about 12 cps.

Embodiment 2

[0243] Formulation of polysilocarbonate formulations obtained using a hybrid approach. The formulation is prepared by mixing 60% of such as figure 1 The MHF precursor shown by the molecular formula and having a molecular weight of about 800 and 40% of the Image 6 Vinyl terminated precursors of the formula shown and having a molecular weight of approximately 9400 were prepared by mixing together in a container and stored for later use. The polysilocarb formulation has a good shelf life at room temperature and the precursors do not and do not react with each other. The polysilocarb formulation has a viscosity of about 200 cps.

Embodiment 3

[0245] Formulation of polysilocarbonate formulations obtained using a hybrid approach. The formulation is prepared by mixing 50% of such as figure 1 The MHF precursor shown by the molecular formula and having a molecular weight of about 800 and 50% of the Image 6 Vinyl terminated precursors of the formula shown and having a molecular weight of about 800 were prepared by mixing together in a container and stored for later use. The polysilocarb formulation has a good shelf life at room temperature and the precursors do not and do not react with each other. The polysilocarb formulation has a viscosity of about 55 cps.
