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.

The results show that glass ceramics with thermal expansion coefficient of 5.11×10^(-6)℃, major phase of α-cordierite and ε=5.5, tan σ=2.1×10^(-4) can be prepared by the addition of 3.6% alkalis (Li2O+Na2O), and Li2O occupies 1.8%. With Li2O substitution for Na2O, spontaneous crystallization is obviously enhanced, and temperature of the first crystallization peak decreases from 950℃ to nearly 900℃, but the crystallization temperature of the second peak was not varied. With the increase of Li2O content, mixed alkali effect can be observed from the thermal expansion coefficient and dielectric loss curve which decreases first and then increases. Dielectric constant decreases monotonously with the increase of Li2O content.
