摘要: 为了判断苯酚-尿素-甲醛(PUF)树脂中原料共缩聚反应是否发生,并确认共缩聚分子形成特点,借助13C核磁共振(13C NMR)和基质辅助激光解析电离飞行时间质谱(MALDI-TOF-MS)两种主要分析仪器,对比研究了苯酚-甲醛(PF)树脂和PUF树脂的结构特点,结果证实了PUF树脂中苯酚、尿素和甲醛3种原料之间共缩聚反应的存在,认为PUF树脂结构以PF树脂为主体,且共缩聚结构主要形成于合成反应初期。

关键词: PUF树脂, PF树脂, 结构, 共缩聚

Abstract: To confirm the existence of co-condensation in phenol-urea-formaldehyde (PUF) resin and understand the development of molecular structure during the polymerization, the characteristic structure of PUF was analyzed based on the study of structure of phenol-formaldehyde (PF) resin with the help of two main instruments 13C NMR and MALDI-TOF-MS. Analysis results confirmed that the co-condensation among phenol, urea and formaldehyde indeed occurred and formed at the beginning of polymerization. The results also confirmed that structure of copolymer mainly derived from PF resin.

Key words: phenol-urea-formaldehyde (PUF) resin, phenol-formaldehyde resin, structure, co-condensation
