摘要
本文提出一种酚醛树脂中羟甲基含量的化学分析法,分别以^(13)C NMR和化学分析法测定酚醛树脂的羟甲基含量.将两种测试结果与已知的投料量进行比较,证明所建立的化学分析法可行.
A chemical determination of methylol group in active phenol-formaldehyde (PF) resins was introduced. Methylol contents in PF resins were determined by 13C NMR and the chemical analysis method respectively. The method was verified to be feasible by comparing analytical results with known formulations.
