摘要：以二乙炔基苯、双(二甲氨基)二甲基硅烷为原料,乙腈为溶剂,通过氯化锌催化实现单步硅烷化合成含硅芳炔树脂。研究结果表明,乙腈做溶剂,二乙炔基苯与双(二甲氨基)二甲基硅烷投料比为9∶8(摩尔比),ZnCl_(2)相对于炔过量0.65倍,回流反应11h效果最佳,收率高达90%以上;制备的含硅芳炔树脂在室温下呈流动状态,加工性能良好,加工温度为40~180℃,加工窗口为140℃;固化后的含硅芳炔树脂,在N_(2)气氛下热分解5%时的温度(T_(d5))为587℃。
A novel one-step synthesis of silicon-containing arylacetylene resin(PSA)was developed via the direct silylation of diethynylbenzene(DEB)and bis(dimethylamino)dimethylsilane.The results show that the optimum reaction conditions:acetonitrile as solvent,mole feed ratio of alkyne and amino is 9:8,the amount of zinc overdose 0.65 times compared with alkynes,and reaction time the processing window is about 140℃.The reaction 11 h.The processing temperature is from 40℃to 180℃,and yield reaches up to 90%.The properties of the resulting resin were investigated.The resin is in a state of flow and has good processing performance at room temperature.The cured resin performs good heat resistance,the decomposition temperature at 5%mass loss in nitrogen is 587℃.
