摘　　要：用热重分析仪、裂解气相色谱-质谱联用仪、红外光谱仪、凝胶渗透色谱仪和差示扫描量热仪分析3种不同生产工艺的间苯二酚-甲醛粘合树脂。结果表明,3种间苯二酚-甲醛树脂的红外光谱基本一致,挥发分、相对分子质量及其分布、结构和链段组成都有一定差异。In this study,the resorcinol-formaldehyde adhesive resins produced from three different production processes were analyzed by thermogravimetric analysis,pyrolysis gas chromatography-mass spectrometry,infrared spectrometer,gel permeation chromatography and differential scanning calorimeter.The results showed that the IR spectra of the three kinds of resorcinol-formaldehyde resins were basically the same;however,the volatile matter,relative molecular weight and its distribution,structure and chain segment composition were different.
