| 中文摘要 | 以D2O为溶剂,采用1H-NMR测定不同醛酚摩尔比的碱性酚醛树脂,结果表明,当醛酚比小于2时,D2O中残余氢峰对树脂特征结构分析无干扰,此时可对分子结构进行定量研究。本文还提出了酚醛树脂分子结构的统计模型,结合1H-NMR测定结果,由该模型推导的方程可以计算出树脂的结构参数。; With D_2O as the solvent, alkaline phenolic resins prepared from different formaldehyde/phenol molar ratios were characterized by ()~1H-NMR analysis. The results show that if formaldehyde/phenol molar ratio is lower than 2, the peak for the remaining hydrogen in D_2O doesn′t overlap the peaks for the characteristic structures of the resin. Under this condition, quantitative analysis of the molecular structure is feasible. Furthermore, a statistical model for analyzing the structure of phenolic resin was provided. In combination with ()~1H-NMR results, structural parameters can be calculated out by the equations based on this model. |
