摘要 以间二乙炔基苯、甲基氢二氯硅烷和苯基三氯硅烷为原料,利用格氏试剂法合成出一种耐高温硅炔树脂聚(间二乙炔基苯-甲基氢硅烷-苯基硅烷)(PDMP)。采用红外光谱分析、核磁共振谱图分析表征树脂的结构、凝胶渗透色谱测量树脂的分子量分布,利用差示扫描量热分析、旋转流变仪研究树脂的固化行为、热重分析表征聚合物的耐热性能。结果表明:随着苯基三氯硅烷与甲基氢二氯硅烷摩尔比的增加,树脂的耐热性先增高后降低。苯基三氯硅烷与甲基氢二氯硅烷摩尔比为4∶7时,合成的PDMP树脂耐热性最佳,氮气氛围中失重5%时的温度(Td5)达654℃,1000℃质量残留率为90.3%,空气氛围中的Td5达574℃,1000℃质量残留率为34.0%。

Abstract:Poly (m-diethynylbenzene-methylsilane-phenylsilane)(PDMP), the heat-resistant silicon-alkyne resin, was synthesized from m-diethynylbenzene, methylsilane and phenylsilane by the method of Grignard reagent. FT-IR, NMR and GPC were selected to characterize the structure of PDMP resin. The curing behavior was analyzed by DSC and rheometer, and heat performance was measured by TGA. The study shows that heat-resistant of resins first increases and then decrease with the increase of mole ratio of phenylsilane and methylsilane. When the mole ratio comes to 7:4, PDMP's heat-resistant is the best. And the Td5 (5% mass loss temperature) and residual are respectively 654℃ and 90.3% in N2, 574℃ and 34.0% in air after 1000℃.
