【摘要】 通过二乙炔基二甲氧基硅烷和间二乙炔基苯有机镁试剂反应,合成了聚（间二乙炔基苯-二乙炔基硅烷）树脂,采用FTIR、¹H-NMR¹³C-NMR对其结构进行了表征,采用DSC和TGA对其性能进行研究。结果表明,其固化反应起始温度较低,树脂固化物耐热性能优异,其T_d5和1000℃质量保留率分别为548.9℃和82.4%。更多还原

【Abstract】 Poly（1,3-phenyleneethynylene-Diethynylsilylene） were prepared by Diethynyldimethoxysilane and1,3-phenylenethynylene organic magnesium.The structure was characterized by FTIR,¹H-NMR and ¹³C-NMR.The curing behavior of the resin was analyzed by DSC and the heat-resistant property under nitrogen was studied by TGA,the resin showed excellent heat-resistant property,its T_d5 and residue rate under 1000℃ were 548.9℃ and82.4%,and it had a low curing onset temperature.更多还原
