【Abstract】 Boron- and Silicone-Containing Phenolic Resin(BSPR) was synthesized by using barium hydroxide and zinc acetate composite catalyst. The structure of BSPR was characterized by FT-IR. Its heat-resistant and flame-resistant properties were analyzed using TGA and Oxygen Index(OI) respectively. The BSPR had high o-o′ methylene structure between phenol nuclei in its macromolecule, and the synthesis reaction was readily carried out due to the lower viscosity of the resin. The BSPR exhibited excellent heat-resistance and flame-resistance, mass loss less than 30% at 800 ℃ and OI larger than 47%. Silicone segment played a significant role on reducing BSPR′s surface energy. Furthermore, some effects on the resin′s properties were also investigated.更多还原
