1.Standard enthalpies of formation of the new monomer salts were calculated using the computationally feasible DFT(B3LYP) and MP2 methods in conjunction with an empirical approach based on densities of salts. 2.The molar degree of substitution of the inorganic and organic acid on polymer 10 was found to fall between 48 and 92 mol % based on elemental analysis data . The partial substitution of acids on the triazole-ring of polymer 10 may arise from difference in acid strengths or from varying degrees of steric hinderance during protonation reactions. Furthermore, the fact that an increase of positive charge density of the polymer salt leads to a decrease in the basicity of poly(1-vinyl-1,2,4-triazole) could be another reason for the experimentalresults. |

2.The molar degree of substitution of the inorganic and organic acid on polymer 10 was found to fall between 48 and 92 mol % based on elemental analysis data . 基本分析数据显示无机酸与有机酸对聚合体10的腐蚀程度减小到48 mol %到92 mol %之间。 The partial substitution of acids on the triazole-ring of polymer 10 may arise from difference in acid strengths or from varying degrees of steric hinderance during protonation reactions. Furthermore, the fact that an increase of positive charge density of the polymer salt leads to a decrease in the basicity of poly(1-vinyl-1,2,4-triazole) could be another reason for the experimental results. 酸对聚合体10的三唑环的部分腐蚀作用可能是源于酸强度的不一致或者是因为质子化作用反应过程中不断变化的空间位阻程度。此外，聚合盐正电荷密度的增加导致poly(1-vinyl-1,2,4-triazole)的盐基度的降低可能是造成该实验结果的另一个原因。 |
