摘　　要：综述了国外研究人员通过理论数学模型模拟线形酚醛树脂的固化行为,运用红外光谱、核磁共振、差示扫描量热、热失重、扫描电子显微镜等不同的研究手段验证了影响固化行为的因素。总结了线形酚醛树脂的改性研究现状,通过加入聚酰胺、甲阶酚醛增容剂来增韧线形酚醛树脂;通过重氮偶合或酯化反应生成阻燃基团,提高了线形酚醛树脂的阻燃性能;通过原位互穿网络法使线形酚醛树脂耐热性和力学性能提高;与无机纳米粒子和片层共混可以提高线形酚醛树脂玻璃化转变温度和热稳定性;结合了线形酚醛树脂和环氧树脂各自优点的环氧酚醛树脂,经改性后性能得到进一步提高。The foreign research work on the curing behavior of novolac-type phenolic resins was reviewed, including numeral simulation and experimental studies using infrared spectroscopy, nuclear magnetic resonance, differential scanning calorimetry, thermogravimetric analysis, and scanning electron microscope. The modification studies on novolac type phenolic resins were also summarized. For example, the toughness was improved by adding polyamide and phenolic compatibilizer; the flame retardancy was enhanced by diazo coupling or esterification; the thermal and mechanical properties were increased by interpenetration, and the thermal stability was promoted by blending with inorganic nanoparticles and layers.
