以丙基三氯硅烷、苯乙炔为原料,通过格利雅反应合成丙基三苯乙炔基硅烷单体（PTPES）。采用傅里叶红外光谱、核磁共振氢谱表征了其分子结构,非等温DSC法研究了单体的固化特性,并运用4种常见的动力学分析方法（Kissinger、Ozawa、Flynn-Wall-Ozawa、Friedman）获得了PTPES固化过程的动力学参数和模型。结果表明,PTPES单体的熔点为75℃,PTPES在固化过程中,符合自催化动力学模型,表面活化能为122.21 k J/mol,指前因子ln A为22.48 s-1,反应级数n、m分别为0.77、0.22。

英文摘要：

The propyl-tri（phenylethynyl）silane（（Ph—C≡C）_3—Si—CH_2CH_2CH_3）（PTPES）monomer was synthesized with propyl trichlorosilane and phenylacetylene by Grignard reaction. The molecular structure was characterized by FT-IR and 1H-NMR. The curing characteristics of the monomer was investigated by the non-isothermal DSC. The kinetic parameters and the kinetic models of the curing process were obtained by Kissinger,Ozawa,Flynn-Wall-Ozawa and Friedman methods. The results showed that the melting point of PTPES was 75 ℃. The PTPES was in line with the autocatalytic kinetic model during the curing process. The average activation energy was 122.21 k J/mol and the pre-exponential factor ln A and the reaction order n,m were 22.48 s-1,0.77 and 0.22,respectively.
