【摘要】 合成了一系列新的具有良好热氧稳定性的二茂铁封头硅油并进行了热性能测试。结果表明,用所合成的硅油作为对普通甲基硅油的添加剂,只需十万分之几的重量份数(按二茂铁计)就可显著提高甲基硅油的耐热性。同时对所合成的硅油用H’NMR 谱测算了分子量。更多还原

【Abstract】 A new series of heatand oxygen-resistant ferrocene-blocked sili-cone oils has been synthesized and TGA has been made.By using abovementioned oils as an additive to methylsilicon oil,we found that theheat-resistance of the methylsilicon oil could be remarkably increasedonly with the concentration of about 0.003%by weight.The molecularweights of ferrocene-blocked silicon oils have also been determinedby H~1NMR.更多还原
