本文研究了硼酚醛树脂的合成与固化反应过程的机理, 结果表明, 甲阶段的硼酚醛树脂主要是硼酸苄酯, 固化过程中形成硼酸苯酯, 反应过程中有醚键生成, 醚键断裂产生羰基。

The chem. changes of HCHO-PhOH-H3BO3 copolymer during the preparation and crosslinking process were studied by IR spectroscopy. Benzoyl borate and dibenzyl ether linkages were formed during the preparation process while Ph borate linkage was formed in the curing process. The formation of carbonyl groups was a result of oxidative cleavage of the benzyl ether linkage.

Key words: REACTION MECHANISM, INFRARED SPECTROPHOTOMETRY, MOLECULAR STRUCTURE, SOLIDIFICATION, PHENOLIC RESINS, BORON COMPOUNDS
