The synthesis and curing property of methyl-tri(phenylethynyl)silane

Keywords： methyl-tri(phenylethynyl) silane , Grignard reaction , non-isothermal DSC , rheology , cure behavior

以溴乙烷、甲基三氯硅烷、苯乙炔为原料,通过格利雅反应合成甲基三苯乙炔基硅烷单体(MTPES),采用FT-IR、1H-NMR、13C-NMR、29Si-NMR对其分子结构进行了表征,并通过非等温DSC法和流变学对单体的固化行为进行了分析.实验结果表明,MTPES的熔点为130℃,加工窗口为200℃,具有较好的可加工性.
