The results show that the atmosphere has a big influence on the thermal stability of C_(60).C_(60) begins to decompose at 423.5℃in the air,the deomposed peak temperature is 668.5℃,but very stable in the helium atmosphere,only sublimate,the crystal shape of C_(60) has a certain influence to its thermal stability.The synthesized nine kinds of nitro-fullerene derivatives all have good thermal stability and their decomposed peak temperatures all exceed 350℃.The thermal explosion temperature for 5 seconds delay of product 4 is 253℃.The category,number and position of nitryl group in nitro-fullerene derivatives all have influence on their thermal stability.
利用差热分析仪和DSC-TG综合热分析仪对C_(60)及其硝基衍生物的热稳定性进行了研究,结果表明,环境气氛对C_(60)热稳定性影响很大,C_(60)在空气中423.5℃开始分解,放热峰值温度为668.5℃,在氦气中很稳定,仅表现为升华,C_(60)的晶型对其热稳定性也有一定的影响;合成得到的九种硝基富勒烯衍生物都具有较好的热稳定性,分解峰值温度均高于350℃;产物4的5秒爆发点测试结果为253℃。

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.
第二部份以2-呋喃甲胺为起始物,制备了P-FBz、4FP-FBz与BPA-FBz 三个含呋喃官能基之氧代氮代苯并环己烷的单体;BPA-FBz与P-FBz於开环聚合中形成之Mannich bridge网状结构有效地提升聚氧代氮代苯并环己烷聚合物之交联密度与热安定性;Poly与Poly具有大於300℃之玻璃转移温度、高的焦炭生成率与具有31之极限氧指数(Limited oxygen index, LOI)的难燃性特质,Poly与Poly之介电常数(Dk=3.21~3.39)与机械性质[3.0~3.9 GPa的储存模数与37.7~45.4ppm之低热膨胀系数( Low coefficient of thermal expansion, Low CTE)]均较其他聚氧代氮代苯并环己烷为优;4FP-FBz具有低之介电常数(Dk=2.7),以其作为降低介电常数之反应型改质剂,与P-FBz混成,证实可有效地降低Poly的介电常数。
