| 摘 要： | 用红外光谱法研究了四种热固性酚醛树脂在固化过程中的化学变化。结果表明热固性酚醛树脂的固化过程,首先是羟甲基发生缩合反应,缩合反应形成醚键是主要的。热固性酚醛树脂在进一步固化时(150—200°)出现了羰基,它的出现不是亚甲基氧化所致,而是部分醚键断裂形成了醛羰基。对热固性酚醛树脂的固化过程的机理进行了讨论。

| Abstract: | The chemical change of four resole type phenol-formaldehyde resins in curing process was studied by infra-red spectroscopy. It was shown that the curing process of resoles, at first, proceeded by condensation reaction of methylol groups, and the formation of dimethylene ether linkage was predominant. During further curing process (150-200°) carbonyl group appeared. The formation of carbonyl group was not caused by the ixidation of methylene group, but was a result of splitting of dimethylene ether linkage. The mechanism of suring process of phenolic resole resins was discussed. |
