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 increasing numbers of soil pathogenic microbes with prolonged planting, the main reason for disease occurrence and spread of soil-borne diseases. Hypogenetic plant, lower photosynthetic rates and enzyme activities decrease self-resistance of the cucumber plant to disease. These form the internal-causes of cucumber disease outbreak. Increases in humidity. decreases in temperature and sunlight are the external-causes of cucumber disease outbreak. The longer the succession, the severer is the spread of soil-borne diseases.
