摘　　要：研制了腰果酚缩甲醛二乙烯三胺(PCD)；并对其固化环氧树脂(ER)的形成过程以及产物PCD-ER的性能等进行研究．结果表明，适量的二乙烯三胺([D]≤7．47％)与PC缩聚制得的PCD，其固化ER的产物，涂膜理化性能、贮存稳定性较佳，尤其具有优异的耐酸、碱性能．红外光谱结果表明，PC中羟甲基先与多元胺中氨基发生缩合反应，接着其侧链氧化交联聚合成PCD；PCD固化ER的过程中环氧基开环与氨基活泼氢发生加成反应，从而引起PCD-ER的进一步交联聚合。An experimental study was made on the process of anacardol aldehyde diethylenetriamine polymer's(PCD)solidifying epoxy resin and the properties of the product of this process,PCD-ER. The results showed that the PCD-ER, obtained by the polycondensation between a proper quantity of diethylenetriamine(≤7.47%)and PC, has better physical and chemical properties in film, better stability of storage, and excellent acidproof and alkaliproof property. The results of Infrared Spectrum showed that first a condensation reaction took place between the hydroxymethy in PC with the aminonaphthalene in multi-amine, then the side-chain was oxygenated and polymerized with PCD. Under the addition of epoxy group in ER and the active hydrogen in aminonaphthalene in PCD, the PCD-ER was further crosslinked and polymerizated in the process of solidification.
