Considering a spherical porous carbon particle immersed in a static ambient atmosphere, the combustion characteristics under three basic conditions: frozen flow, equilibrium flow, partial flow are solved in a half-analytical and half-numerical way. By using the LAEA (Large Activation Energy Asymptotic Method), the departure value of some parameters such as combustion rate, temperature, and concentration are obtained. On this basis, the rules of a carbon particle combustion under various conditions when the gas phase Damk〓hler number is in the range of 0,+∞ are summarized.

Good thermal stability and self-extinguishing behavior was observed with the cured polybenzoxazine resins. Second, furan-containing benzoxazine monomers, P-FBz, BPA-FBz, and 4FP-FBz were prepared using furfurylamine as a raw material. Formation of furfurylamine Mannich bridge networks in the polymerizations of P-FBz and BPA-FBz increased the cross-linking densities and thermal stability of the resulting polybenzoxazines. P-FBz and BPA-FBz- based polymers also exhibited high glass transition temperatures above 300℃, high char yields, and low flammability with a limited oxygen index value of 31. The dielectric (Dk3.21–3.39) and mechanical properties (high storage modulus of 3.0–3.9 GPa and low coefficient of thermal expansion of 37.7– 45.4 ppm) of the P-FBz and BPA-FBz-based polymers were superior or comparable to other polybenzoxazines. 4FP-FBz used for polybenzo- xazine modification by means of formation of benzoxazine hybridation with P-FBz.
